Recent Tutoring Session Reviews
"I explained how two factor ANOVA worked and we completed her homework assignment on it. She was actually tasked with computing an entire two factor ANOVA table. She stuck to the formulas and was able to fill it out. We talked about the 3 different hypothesis tests that are involved in two factor ANOVA and how to make a decision about each."
"We went over problems on the practice final in preparation for the student's final tomorrow. He seemed to be ready for the test."
"For our first session, we went over a study guide with concepts related to random variables. We started by discussing a sampling distribution vs. an overall population distribution, with a special focus on identifying when the former is approximately normal in shape. From there, the student completed several problems in which the student found the standard deviation or mean of a random variable (either discrete or continuous). In addition, we went over confidence intervals. This led into a discussion about the actual "meaning" of confidence, as well as the different factors and components of a margin of error."
"Today the student and I worked on confidence levels. We talked about how to find the appropriate z-value and she did very well solving for the interval. We also talked about ways to make an interval more narrow and what that means for sampling. We also worked ahead and talked about margin of error and sample size determination. She is able to help her friends with their questions, which is great practice and shoes she has a good working understanding of the material."
"We reviewed all material in preparation for Tests, covering T-tests, Z-tests, T-intervals, and Z-intervals. We reviewed when we reject the null hypothesis and accept the alternative hypothesis. We worked through how to do problems on the Ti-83 and by hand."
"We went over performing three different kinds of t-tests, f-tests, and three different kinds chi-squared tests. The student needed someone to walk him through the steps of performing these statistical tests. I taught him key words to look out for in questions that inform him what types of tests he would need to perform, and the common steps involved in each statistical test. As usual, he picked things up pretty quickly, and I told him that he should give himself a little extra practice by just making up some fake date."
