Recent Tutoring Session Reviews
"We covered two sample t-tests for significant differences in data sets. Part of the session was spent defining key concepts (null hypothesis, alternative hypothesis, p-value, t-statistics) and the remainder was spent solving homework problems using tests of statistics in Excel. The student was very excited when the proverbial light bulb went on after she solved a particularly difficult problem. She was challenged by creating output tables from t-tests, but she worked through an example and experienced success by the end of the session. We will continue next time with two-sample tests assuming equal variances."
"Today, we reviewed a lot of material for the student's next test. We went through working "and" and "pr" probabilities, probability distributions, permutations, regressions, and binomial problems. I gave the student some general rules that will hopefully help her on her test day."
"We covered the student's homework assignment which included probabilities using the multiplication and addition rules. The homework also covered both dependent and conditional probabilities and the use of Venn diagrams to calculate some of these probabilities. Additionally I explained a general method for calculating probabilities based on the counting principle. That is, P = number of desired outcomes/total outcomes and used an example problem of selecting a particular subset from a multicolored set of objects. I demonstrated use of the TI-83 in calculating combinations nCr."
"The student and I reviewed her most recent exam and some concepts she did not seem to grasp. Most of our time was spent working out some practice problems for the PSAT. She had difficulty with certain concepts needed for SAT/ACT success, so I gave her the assignment to work problems in her ACT practice book and to make flashcards with certain facts that are needed to quickly arrive at answers to SAT/ACT questions. She also needs to purchase a new graphing calculator as she needs to learn on the device she will be using for exams."
"The student has been doing well in class, so we decided to move ahead in the course. I worked with her on using the First and Second Derivative Tests to find characteristics of functions. I also taught her how to use the Concavity Test and how to use it to graph the original function. Finally, we briefly went over applying first derivative tests to optimization problems. She picks up new material well, so she won't struggle with this material in class."
"When I arrived, the student told me that he has improved in his test score and did well. Because he has a PSAT on Wednesday, and since he had a PSAT training exam, today we went through reviewing concepts of arithmetic, algebra 1, algebra 2, geometry, and statistics. He could see the solution for some problems he forgot how to solve. Overall, he had a better understanding of the kind of problems and methods of solution he will face on the PSAT."
