Recent Tutoring Session Reviews
"For our last session we continued working on correlation (assessing strength, direction, and significance; reading correlation matrices; drawing conclusions about relationships) and extended into effect size (specifically, how correlation is a measure of effect size and how it relates to R^2, or proportion of variance explained and what that means conceptually as well as how to calculate it). The student has made great progress understanding the concepts of statistics."
"During this session, the student and I reviewed the concepts covered on the 2 most recent exams given in her course. It covered tables, testing, and finding the variance in differences of means. The other exam covered constructing null and alternative hypotheses, and how to prove whether or not the data was statistically significant to reject or accept the alternative hypotheses. We went over each question on the exam, and trouble shot any issues that she had, going over sections in the book or notes on how exactly to attack the problems. I think this was an effective way to review for her final because we went over what will specifically be on the test and reviewed half of the semester at the same time. She was receptive for the session."
"Today we went through the regression outputs - which I will match to hand calculations - for the chi-square two sample test (1), the T-test for independent samples (2) (which I will also match to hand calculations), the simple regression (3), multiple regression (4), simple regression (5), and chi-square two-sample test (6). I will be sending interpretations via email to check over this weekend!"
"The student and I reviewed counting techniques, permutations and combinations. In our next sessions, we will discuss expected value and binomial distribution, as well as prepare for her final in the course."
"The student and I did some final review for her final exam. We most heavily covered probability and went over some of the trickier probability concepts like conditional probability, at least problems, and non-disjoint events. I think she will do great on her final exam and she has shown great improvements over the duration of her course."
"The student and I continued discussion of the student's HW. We focused on exploratory data analysis, computing descriptive statistics, various plots, and confidence intervals."
