If you select this option, WyzAnt will ask interested tutors to contact you by email if they are able to help. A maximum of five different tutors will email you and none of your personal information, including your email address, will be released.

I am a Ph.D. statistician, and I have a long experience in teaching mathematics and statistics as a university professor (grad and undergrad level) as well as a research/statistical consultant. I strongly believe that I have the skills, experience, and training required to communicate mathematical and statistical results to very diverse individuals and audiences.

I am also very proud that my WyzAnt student for two consecutive years was accepted to MIT!

Because of my training and experience, I am specialized in teaching mathematics and statistics, so these are the only subjects I tutor. I want my students to get high quality services, related to my area of expertise. I am happy and proud that I have helped numerous students with a variety of courses ranging from AP Calculus and AP Statistics as well as graduate and undergraduate college level. Additionally, I can effectively help you with any type of statistical software as SPSS, SAS, R, and Stata.

Having a long experience in statistical consulting, I can provide high quality assistance with the research design of theses, statistical projects or with the statistical analysis and software implementation of other research or professional tasks.

Minimum 60 minute session for all lessons.

I understand that things happen, but to be able to accommodate my students, I have a 24-hour cancellation policy. If you do not cancel a lesson before that period, I will have to charge an one-hour cancellation fee.

Elena replied on 6/5/2014

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.

Approved subjects are in bold.

Approved subjects

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.

Biostatistics

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.

Logic

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).

Praxis

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.

SAS

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.

Outstanding tutor! — 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 har ...
