Dr. R has the unique ability to make the complicated seem straightforward and understandable without making the student feel like an incompetent. Math/Stats can be intimidating for the 'math challenged' but it is key to being a complete social science student. My adult child was having a hard time with the stats, and despite studying and seeking help from the professor and TA, it was still too hard. Dr. R has made all the difference. Would highly recommend her to other students.
Ability/Knowledge: A+; Time Flexible: A+; Responsiveness: A+; Ability to communicate with all levels of student: A+
If you are a Undergrad or Graduate student, No need to suffer through Stats. Pick Dr R.
I first started my lessons with Elena during the first year of my doctoral program. She has tutored me in content related to my graduate statistics courses including advanced statistics, and multivariate statistics. Elena is able to simplify statistical concepts to even those that may not have the strongest math backgrounds. She is excellent in explaining how to run analysis in SPSS and interpreting them. Elena is dependable, thorough and very much concerned about her students mastering the material. I credit Elena a GREAT deal in regards to my success in statistics. I HIGHLY recommend her for any undergraduate or graduate student who may need additional assistance in statistics.
My sense was the tutor may not have considered closely all the materials I submitted about my particular problem and my work on it to date. I feel like I received general information (some of which was already in the detailed problem statement I originally submitted) in return for the $170 I spent and I feel like I made virtually no progress toward answering my principal question. It's possible a breakthrough would have occurred if I had invested additional hours but my hunch was that wasn't going to happen so we wrapped things up where they were after 2 hrs 10 min charged for strictly e-mail tutoring. Tutor responded quickly and was very professional. I think this just wasn't a good fit for the particular problem I'm working on.
Thank you for the feedback. I just wanted to clarify that the response I sent you was the answer to a very specific question you asked (which one of the three numbers is the correct calculation for the variance). The general information you are referring to, was the justification (the theory behind) this answer, which I always provide to my students. In addition, the correspondence (tutoring) via email was used upon mutual agreement since you live in NM and I am in MD. Thank you again, I really enjoyed working with you.
I really can see an improvement in Stats from my first class, and she is well qualified. I am so thankful that I found Ms. Elena. She was on time and is well prepared. She is the best.
She does not take much time to review (other tutors do) before jumping right into tutoring. Very smart.
Always prompt and on time.
Elena is the best! Without her I don't know how I could have passed my class. She is very nice, patient, and explains everything in a way that you would understand. I started out with hating SPSS to actually liking it and understanding it, thanks to Elena. If I ever have a statistics class in the future or anything math related I will 100% be calling Elena. She is definitely the best and she knows what she is doing. Thanks for everything Elena.
One of the best tutors I have ever had. Extremely patient, knows her subjects in and out, and always makes herself available to her students. Cannot recommend her highly enough!!
Elena was a very clear and helpful tutor. I came in, told her what I wanted to go over/practice, and we went ahead and did it. She was a huge reason I was able to pull off a B in a class where the average grade was in the C/C- range. If you need Calculus help, Elena is a great tutor.
I was taking a Masters level Statistics and Quantitative Methods college course for an MBA program at an AACSB accredited business school.
Midway through the course I had a 74, which is a C. In the MBA program getting a C means you have to retake the course and may land you on academic probation.
Elena is a college professor at a local university, not the same university as me, teaching statistics.
I contacted about ten statistics tutors from WyzAnt and none of them could help me with my masters level statistics course, except for Elena.
They simply did not have the education or skill set for this advanced course and with the class half over I needed help right away. I contacted Elena.
Elena tutored me on a weekly basis: we reviewed my homework answers, reviewed the practice exam problems, and worked on my empirical research paper together.
By the end of the class, my grade had improved from a 74, which is a C, to an 85, which is a B and I passed the course.
Without Elena's tutoring, I would never had passed the course and I would have had to retake it over the summer.
I am a student working on a doctorate and was so grateful for the help and guidance I received from Elena. She guided me through my Chapter 3 methods section and I was able to pass IRB review with flying colors. I also received her help with Chapter 4 and my statistical presentation of my research data. She has a great grasp of grammar too, which was a big help on the flow of this chapter. I highly recommend her as a doctoral tutor.
Professor Elena has always been very patient with me when I had to ask for clarification on the same statistic problem more than one. She always wrote the problem out on paper in a clear manner which helped me to better understand and review the problem again after the tutor session.
I recommend Professor Elena to students who need assistance in Statistics.
Elena is very responsive to her students and is easy to communicate with. She has a great level of understanding in Mathematics, particularly in the subject I needed help with, Statistics. I would recommend her for any college math student preparing for a final exam or even a normal exam. Elena can meet close to the student and is well worth the hourly rate.
Elena was great! She helped me calculate situational probabilities for binomial model and normal distribution. Elena also assisted me with testing statistical hypothesis about population mean and proportion and by using either the z test or the t test. She guided me through the problems and made them understandable. She was available on short notice. Thank you Elena!
Elena fills in the large gap between the limited insight the books give and lack of time instructors have for question and answer. To learn math effectively, you need to ask a lot of questions at your own pace. On-line videos give a lot of data but no test for understanding as are most classroom environments. Having an excellent tutor like Elena keeps me from getting lost or behind the class in accelerated course work. She asks excellent questions to see what I already know and then works with me to understand the missing elements I need. It's the best value of my educational funds to date.
Elena assisted me in conducting a statistical analysis research project. She was not only patient with me but also took the time to make sure I understood the concepts and results. She is always available to help and guided me in a way that my own professor could not. I will be forever grateful!
I was having a very difficult time with calculus and honestly, she taught and explained the material that I hadn't learned in a month. She took great notes and I was able to keep it for future reference. I highly recommend her.
Elena was able to help me understand some of the difficult biostatistics concepts being covered in my course. I wish the service were more affordable so I could take advantage of her wonderful tutoring.
Excellent. She goes strait to the point. Extremely organized and knows how to translate a hard subject in a easy language. A wonderful lady and tutor.
Elena was very good at explaining complex math concepts in understandable terms and shared tips on how to speed up my work on solving math problems.
This is my second session with Elena. She helped me most recently with some problems I was having with descriptive and inferential statistics. She is very patient, and more importantly she knows her stuff. She explained the concepts to me in a way in which I had not understood them previously (even after consulting with a textbook and a course professor), and after our hour session was over I had a much more thorough understanding of statistical concepts. I would highly recommend Elena if you have any questions about statistics!
Elena is a true gem when it comes to being able to break down Statistics to its bare components so that even the most challenged student can understand and follow her lead. She was wonderful at explaining one/two tail hypothesis testing and ANOVA and regression models. She helped me work through practice problems and shined light on concepts my teacher discussed in class. Well worth the investment! I will continue to call on her for assistance as I progress through my class.
Elena really works through all of the problems with you and gives great advice for self-study. She goes over exactly what is needed and is great for exam help.
She did an outstanding job on helping me with Calculus, Discrete Mathematics, Modular Algebra and Statistics for Engineers. She has a very deep understanding of Math and is even better at teaching others. She can make complicated formulas simple to follow for absorption. She was flexible to accommodate my schedule of working midnight to eight shifts then back to normal working hours. It had been 14 years since I took any Calculus and she helped me remember and learn new concepts. I would use her assistance again if the need arises. I would highly recommend Elena for any math tutoring especially statistics and calculus, which are her strongest subjects.
I am a graduate student who was required to take a statistics class and quickly realized that it made no more sense to me now as it did in undergraduate school. Elena is very responsive, flexible and accommodating. Elena helped me with understanding what the stats mean in research articles and how to write and understand research hypothesis. She has the ability to meet you at your current level of understanding and explain the concepts to you in a manner that is clear and concise. Elena is very patient and her communication style is one that makes you feel safe to ask questions.
Elena was exactly what we were hoping for in a geometry tutor: patient, punctual, and a supportive teacher. Elena was always willing to be flexible with our changing schedule, and my daughter's
grades went from C's to A's. What more can you ask!?
My daughter struggled with math. When Elena started with her she was in danger of getting D in the first semester while at the end of her junior year she has solid B. Her math improved significantly under Elena's tutoring. Elena also helped my daughter with preparation to ACT. Elena is very responsive; any time my daughter needed extra help Elena would find time to accommodate our request.
Pleasant. Stays on topic and does not waste time. Knows how to work the software program (SPSS) well for dissertation.
Elena helped me through a college precalculus course. She is a very helpful, patient, and kind person who has a great understanding of mathematics. I would recommend her to anyone who wants to increase their math skills and perform better in class.
We hired Elena to help prepare my son for the Calc BC AP exam. She was dependable, extremely flexible in her hours and helped my son with exactly the topics he needed assistance with. He enjoyed his sessions with her and felt comfortable when taking the exam, which was exactly what we wanted. We would definitely recommend her.
Elena was able to explain some concepts I was having difficulty understanding very easily. She was a great tutor, easy to work with!
Elena tutored me in Business Statistics 2. I got a B in Business Statistics 1 on my own, but, I had heard horror stories about Business Statistics 2. I figured I better get a tutor. I'm sure glad I did. She did a great job helping me and walking me through some problems I was having trouble with. I spent a lot of time on my own going through the chapters and examples on my own first, and asking my instructor for help as well. I then utilized Elena's skills to help bridge the gap, or explain things that I was having trouble with. I would definitely see Elena again. I don't think I have any more math/stats classes left, but, if I do, I'll be sure to give her a call.
Thanks again Elena!!
I was very pleased with Elena. She has a very calming and helpful approach working through concepts. She is clearly knowledgeable and familiar with teaching. I have continued to work with Elena and she has continued to impress me with her abilities to provide meaningful instruction. In particular, she has provided additional aid with my capacity to use the TI-84 calculator.
I just want to share that Elena is an amazing tutor. I've learned so much in the few weeks since securing sessions with Elena. Aside from her knowledge/expertise, she has a warm bedside manner where questions and concerns are welcomed. If anyone is looking for an amazing tutor I strongly encourage/recommend Elena.
Elena is a treasure. She knows her stuff and most important my daughter likes her a lot. We are fortunate to know her.
Elena is a great tutor. She is not only very knowledgeable and experienced in tutoring/teaching, she is also very patient, flexible and helpful in meeting our needs even when sometimes that were not convenient to her. She is really willing to help the students to improve, and my son's statistics study has been improved greatly. I highly recommend her to other students.
I am a PhD student who has had statistics a number of times in the past during both my undergraduate and prior graduate work. I can mechanically do statistics and have always had very good grades in prior courses, but, I want to understand what I am doing and begin to develop a deeper knowledge of the subject since research will be a part of my future. My class this term has about 15-16 people in it with various degrees of knowledge and comfort with the subject - my professor is actually quite capable as well.
Elena has been fabulous in helping me build this deeper appreciation and explains things at a level in which I can appreciate the material more. She is patient and very knowledgeable of the subject and is skilled at giving feedback.
Dr. R. is a very patient, careful tutor in precalculus. She stepped in during the holidays and gave my high school junior the confidence to successfully raise his grade during exams. Elena R. is a gracious individual with impeccable credentials. She was a welcome visitor in our home and we appreciated her efforts to instruct our son. I highly recommend her!
My senior daughter is at a private school who takes AP CALCULUS AB.
Elena has been an excellent guide for my daughter. Elena is very patient and thorough yet firm. Also, she is very quick to respond through phone and text and most of all, she helped my daughter's confidence level in math!
We highly recommend Elena.
I am SO thankful that we decided on a tutor. My 11th grade son struggled with failing grades in his AP Calculus class. With Elena's help he was able to go from a "F" in his first quarter to achieving a high "B" on the semester exam! Elena is amazing! My son regained his confidence and he will be able to exit the year with very good grades! We're back looking at colleges!
Elena was absolutely awesome! Not only was she flexible with her schedule and willingness to work with me, she made statistics appear simple!
Elena, I can't thank you enough!
Elena was a excellent tutor. She provided step by step methods to help me understand Stats! It showed she loves what she does. Overall,great tutor!
Elena is a great tutor! Very knowledgeable and patient. She helped me get an A in statistics during my MBA program. I would highly recommend her. Well worth the cost!
At the doctoral level the requirements are exacting and the opportunity for mistakes few. Elena's patient and expert guidance and review was instrumental in my successful completion of an advanced statistics course. From theory to software applications to reporting and professional writing, Elena provided critical critique while reinforcing my understanding of the procedures. From the perspective of an adult learner, Elena offered the perfect level of support. I would seek her out for further assistance.
Elena is one of the best tutors you will ever find. She is a wizard in the subject of statistics. She is very good at simplifying the problems and making it easy for anyone to understand. I would have not passed the course if it was not for Elena. If you are a student and need someone to help you succeed, do yourself a favor and contact Elena. She is very professional, dependable, and flexible.
I enjoyed working with Elena, She has a Ph.D. and she knows what she is talking about. I had her as a tutor for my graduate course in statistics and she made stuff clear for me. I did not even have to meet her as often because her explanations were really good and I was able to repeat her instructions on my own. I aced my class and I met her the day of...she made time for me early in the morning the day of my final to go over my weak areas. So don't let the money hinder you from getting some valuable help and possibly acing your courses because failure is more costly than getting a tutor.
I contacted Elena on short notice and she was able to meet with me and help me with my assignment. She was very helpful and was clearly very knowledgeable. She took the time to explain the concepts that I had trouble with and was very easy to work with. I would recommend her to anyone looking for assistance in her field. She helped me collect data for my political research paper regarding SPSS. She even emailed me with detailed information for my questions after the meeting.
Elena helped me with my statistics homework, and it was really great! She is very knowledgeable and patient, and her explanation was very clear! I am definitely scheduling another lesson soon!
Easy to reach and arrange a session. Doesn't waste time and has great proficiency in teaching, in this case Calculus.
Elena is tremendously knowledgeable, patient, and a wonderful tutor. If you need help with statistics, Elena is DEFINITELY the one to contact.
Elena did an excellent job reviewing and explaining the principals of interpreting statistical analysis of SPSS data. She is clear and easy to follow in her explanation.
In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.
I have an extensive training in biostatistics, and in particular in topics related to worked in survival analysis, biomarkers evaluation, missing data and proportional hazards models to name a few. My experience is related to the numerous biostatistical projects that I have been involved, as a consultant, through the years and the numerous students and professionals that I have helped both with the software implementation and the analysis of the results.
I have taught logic as part of a quantitative reasoning undergraduate course and as part of a finite mathematics course. These courses include but are not limited to the discussion of statements, premises and conclusions, negation, conjection and disjunction, conditionals, necessary and sufficient conditions, contrapositive statements and equivalence. The combination of all these leads to the construction of truth tables for analyzing statements and determining their validity (tautology).
I have successfully helped numerous Praxis candidates with all of the Algebra, Geometry, Trigonometry and Calculus parts of the test. I can provide students with not only the analytical approach to the questions but also with the right strategies to ace the test. The most important such strategy is time management. To achieve the best results possible I train students to effectively use scientific/ graphing calculators such as the TI 83-84 series. By doing that the student can deliver excellent results in the minimum possible time.
Besides a long experience I have as a SAS programmer and my participation in numerous statistical projects using SAS and SAS Enterprise, I have recently passed the programming 1 and programming 2 courses (offered by SAS) so that I can more effectively help those people that are seeking SAS certification. i have also taught a University course related to experimental design with the use of SAS.
Elena R. passed a background check on 4/22/14. The check was ordered by Elena through First Advantage. For more information, please review the background check information page.
After sending a message to Elena, you will be able to order a new background check for $7.99. As part of your tutor selection process, we encourage you to run updated background checks. Please also review the safety tips for hiring tutors.
