Are you preparing for the PSAT, SAT, & ACT quantitative exams?
So are we!
My name is Paul J. and currently I have 3 students in Vero Beach, Florida who are preparing for these exams this summer. We are looking for motivated students to join us for private lessons. A limit of 5 students has been placed, so there are only 2 positions available.
Lessons will cost $30 an hour, and we plan to do 2 one hour lessons a week for 5 weeks starting in early.
Our goal is to score well enough to compete for scholarships such as Bright Futures and the National Merit Scholarship.
If you are interested, please message me on my WyzAnt Profile.
As with most college students, statistics is a really hard subject to grasp, even for somebody that is good in math (i.e. algebra,calculus, etc.).
What one needs to realize is that although a good foundation in mathematics is needed to truly understand statistics, the concepts behind the use of statistics is actually quite simple.
Since I have always enjoyed hunting and fishing, I always love bringing up the example of the mathematicians and statistician that went hunting.
So, 2 mathematicians and a statistician went hunting for deer. Both were standing in the same stand and talking about all the fun things in life, when all of a sudden the biggest and nicest buck on the property staggered into the area.
The first mathematician pulled his bow back and shot towards the deer. Unfortunately the arrow missed it's target high and the mathmatecian became really sad. Reveling in this new found opportunity,...
The general form for a box-and-whisker plot is really easy. Let's take a simple data set.
8.2, 15.9, 12.8, 7.4, 24.7, 23.2, 9.6, 7.9, 8.3, 10.2
First, we need to take those data and put them in numerical order. When we do that, this is what the data set looks like:
7.4, 7.9, 8.2, 8.3, 9.6, 10.2, 12.8, 15.9, 23.2, 24.7
[Note: Any computer program that runs spreadsheets or statistical analysis will probably accept the data in any sequence. Ordering the data is only necessary when doing this process by hand.]
Once ordered, we need to find the median of the set. The median means the "middle" value. In this case, the set has 10 values, so there's no singular "middle" value of the set when ordered least to greatest. To create one, we'll take the two middle values and average them.
(9.6 + 10.2)/2 = 9.9
[The only reason we took an average is because there is not "middle"...
When conducting a group of statistical comparisons, it is important to understand the concept of familywise error or the 'familywise error rate'. The concept of familywise error describes the probability of incorrectly rejecting the null hypothesis. Perhaps more informally, familywise error represents the odds of reporting a statistical difference when no such difference exists.
To understand why familywise error is important we must revert back to concepts learned in a basic introductory statistics class. First, we generally compare t-values (or other test statistics) to a known distribution of scores (t-scores in this case). Like any distribution, some values near the center of the distribution are more likely to occur than others. By understanding the odds that a given t-score will occur, we are then able to designate values that define regions of the distribution that are unlikely to occur as "critical values". That is, values above or below these critical values...
I'm so glad my GMAT student improved upon his score!! He's in for BIG things...
Now, I'm looking for college students to tutor! I want to see even more successes this year!!
There is is a reason the student-to-teacher ratio was small in ancient times. IT WORKS!!! :)
Statistics Class is one of those oddball math classes because it is one of the first university level math class that a student will take. See most students coming into statistics have gotten into the
Stats does not necesserily act like that because stats is more labor intensive the first week. Most of the information though is only required on the first test but is necessary for the rest of the semester. For instance Statistics is the math where students COLLECT, ORGANIZE, ANALYZE AND SUMMARIZE large amounts of data.
If students studied that definition just for a second, they know what the rest of the semester is going to bring them, but we will continue that in a different posting.
First important thing to notice is the title of my blog. PPSS
This is probably the most important item you need for class because it is arranged...
See if there is one thing that I cannot stand, is seeing a student rush into a Stats class and stating that this class is remarkably easy because my friend said so. Too many times has a student come up to me and asked is statistics easy, and I reply "it most certainly is... for myself, because I studied my content for two years before retaking the course.". If you know that you are going to start a statistics class anywhere at any time your going to need the following items.
1. TI-83 or 84 preferably
Now why one of these calculators? Students, if you are going to take a stats class be aware that there is a lot of data or numerical values that can be used to find the measures of central tendency and measures of dispersion.
These calculators excel for data entry and double checking your answers on the very first test.
*If your teacher says you cannot use this calculator, then get its cheaper cousin.
Hint there usually...
You can find some really good resources for math test prep in the used bookstores in a college town. Some examples that I like are: (1) Humongous Book of ______________ Problems (fill in the blank with your math topic); (2) the REA Problem Solvers series; and (3) the Schaum's Outlines. If you don't live near a college town it might be worth a Saturday trip just to buy books. Alternately, all of these are available (used) through the Amazon Marketplace sellers at really low prices.
You should preview each title of these book series that you might be considering to be sure you like the authors style. Each one is different. You may like one series' treatment of Pre-Calc but prefer a different series for Calculus.
So how do you use these books ?
They are an alternate resource for explanations of basic concepts and problem solving techniques. You should use them as 'hint mills' and sources of problems to make...
This is a response to: How did you master a subject or concept that challenged you in school?
For me, the biggest academic challenge in school occurred when I took a required graduate statistics course. In this program, there were two semesters of stats required, and I did just fine in the first semester. In fact, I really don't remember been scared at all. However, there was a big fear among all the first year grad students going into the second semester of the course with a very famous faculty member who actually authored the textbook we used. The man seemed nice enough, yet I was terrified. In class, I took down every note, but after class, it appeared to be written in Chinese. I tried recording the lecture; still, there was little progress. I joined a study group, and it was clear that everyone was equally lost. In fact, most of their fears INCREASED my anxiety. Going into the midterm, I experience a family crisis....
Many statistics students have likely heard their instructor say the phrase, "correlation does not mean causation." As a statistics student, you may have even recited this phrase during a discussion or included the phrase in a written assignment. But what does this phrase truly mean and why do we care?
Consider this scenario:
A researcher wants to examine the impact that watching the show "The Jersey Shore" has on an IQ test performance for a class of Introductory Statistics students. To investigate the relationship, the instructor surveys the classroom and asks students to 1) answer some questions that will be used to calculate their IQ and 2) indicate the amount of time (in hours per week) they spend watching
The Jersey Shore. The instructor compares the responses for hours spent watching
The Jersey Shore to student performance on the IQ test and finds a strong, negative relationship, r(30) = -.45. Remember, a strong negative...
Before I go run a marathon, play with my family at the pool, ride a roller coaster, head to the beach, or eat some serious amounts of ice cream, I will look back on the successful school year I have had.
I got to tutor over 15 students in Middle School, High School, SAT, and College Math...and even Chemistry! I watched GPAs rise for everybody-some were happy just to pass that College Math course to graduate, others enjoyed their hard earned As that were brought up from the D level. I must say, that things did get crazy with exams at the end of the year, but it all worked out amidst our busy-ness.
My tutoring schedule is light for the summer, and I am hoping nobody waits until December exams to contact me! I want things to be done the right way...after all of the swimming, adventure, and ice cream, of course! :)
Now that students, teachers, parents and tutors have had a chance to catch their breath from final exams, it's time to make use of the weeks we have before school starts back. Consider all that could be accomplished in the next few weeks:
Areas of math that students NEVER REALLY GRASPED could be fully explained. This could be
elementary skills like adding fractions, middle school topics like systems of equations, or
high school areas like sequences and series.
Students could have a TREMENDOUS HEAD STARTon topics that will be covered in the first few weeks of school. Imagine your son or daughter being able to raise their hand to answer a question in the first week of school because they had worked several problems just like the ones that the teacher is demonstrating.
ENORMOUS PROGRESS could be made in the area of preparation for the standardized tests (PSAT, SAT, ACT and more) that are so important to getting into a great college.
I have been working with a few students who are ready to learn math much, MUCH faster than allowed by the traditional classroom model in which math is taught over 6 to 8 years. Based on this experience I believe that many students as young as 4th grade and as old as 8th grade (when starting in the program) can master math in 2 years from simple addition through the first semester of Calculus, with Arithmetic, Algebra 1, Geometry, Algebra 2, Precalculus, Probability, Statistics, and Trigonometry in between.
This is significantly faster than the traditional approach and is enabled by a combination of one-on-one teaching and coaching and a variety of media that I assign to students to complete in between our sessions. This is a "leveraged blended learning" approach that makes use of online software, selected games, and selected videos with guided notes that I have created that ensure that students pick up the key points of the videos, and which we discuss later. The result...
This is a wonderful place to learn about different STATA code options. I personally found it very helpful when learning STATA:
Congratulations to Scott W for passing all of your classes and getting very good grades, in even the very challenging subjects!
Congratulations to Niesha for getting an "A" on her Operations Management final exam. That was a challenging class, and I know you worked hard for your good grades. I am so proud of you for your dedication and resulting success. Keep up the good work, and before you know it, you will be graduating!
Good luck with finals everybody! Hope you get A+'s!
As you may know, I am a big fan of the well-known author and brain specialist, Dr. Daniel Amen. He mentions in several of his books that Physical Exercise is good for the brain. I have read of research studies that showed a clear correlation between IMPROVEMENT in students' test scores in math and science, and their level of physical activity (for example, when math class followed PE class, the students had significantly higher scores). Maybe we should schedule PE before all math classes in our schools. What do you think about that idea?
This morning I read an online article on the myhealthnewsdaily site, entitled "6 Foods That Are Good for Your Brain," and another article about how Physical Exercise helps maintain healthy brain in older adults too. The second article, "For a Healthy Brain, Physical Exercise Trumps Mental Workout" was found under Yahoo News.
The remainder of this note is quoted from that article:
Regular physical exercise appears to...
My recommended strategy to Students at all academic levels for learning and successfully passing the course at all modalities (on-line, on-ground) is the culmination of at least ten years of teaching and tutoring statistics at the undergraduate, graduate, and post-graduate levels in business, management, sciences, social studies, and psychology. It consists of the following:
1. The first is to learn how to overcome fear and anxiety from the unknown and look at tutoring as a prudent investment to your immediate future and success. Engage the tutor from the start of the course and don't prolong the decision because of the complexity and quantitative nature of the subject area. This component of the overall strategy is to keep the weekly normal pace and retain basic real life knowledge for ongoing participation in the political and economic process of the National affairs and State-of-the-Union.
2. Academic Reading Materials and Study Guides encompass three distinct sections without...
If you get stuck doing homework problems often, have a hard time doing your classwork, or sometimes you just can't follow your lecture notes try going to Wolfram Alpha. Wolfram Alpha is a computational knowledge engine that is designed to handle mathematical problems and computation, and scientific problems. It has its limitations but it is a really awesome tool that gives a lot of detail when you need it. Try it out for yourself.
