Recent Tutoring Session Reviews
"In this session, we covered various topics related to probability distributions (normal, t, chi-square, binomial, and F). We also reviewed a chi-square test for goodness of fit, test of independence, and linear regression. This student was pleasure to work with."
"The student and I worked through some more of her homework and then also through a post-chapter review. This whole chapter was on probability and probability distributions. We discussed finding the mean and standard dev for different probability distributions, as well as using the calculator and the binomial function to help the student move through the material more quickly. She already seemed to have a much better grasp of the material than just a few days ago when we started to work on it."
"The student completed the sixth tutoring session aimed at improving her understanding of statistics. During the session, I helped her review for her upcoming statistics final. When asked to identify the concepts she struggled with the most, she indicated that she had found randomness and probability to be the most challenging. As a result, we reviewed both of these topics. After discussing each topic, she was asked to solve a series of relevant problems to check her understanding. She was initially asked to solve each practice problem independently. If she provided an inaccurate or incomplete response, I pointed out her errors and asked her questions aimed at guiding her toward the correct answer."
"The student provided updates related to his upcoming final exam, including the format and content. He requested to spend this session completing his unit 4 homework, and the next session reviewing for his final exam. We reviewed how to calculate marginal and conditional distributions and relative frequencies for table data sets. He had a good understanding of how to compute the percentages, and I suggested that he check all of his frequencies by adding them up to 100% (or 1 for decimals), to ensure that he did not make any mistakes deriving the totals. We also discussed how to interpret these frequencies, depending on the explanatory variable and the overall trend of the data findings. I advised him to review his homework, particularly his explanations. He was attentive and cooperative throughout the session."
"The student used TI84/84 calculators to answer homework problems using statistical analyses involving correlation and linear regression. At the end, I gave an overview of some of the basic statistical tests that a graphing calculator is capable of, t test, 2 sample t test, ANOVA, and linear regression."
"The student wanted to go over the problems she still didn't understand from previous problem sets, so we covered a couple different topics in this session. We worked on finding one-tailed probabilities, constructing confidence intervals and hypothesis testing. She had some trouble identifying the correct formulas to use in a given situation, but she has good notes and when she took the time to read through them, she could usually figure it out on her own. Most of the problems we did were about binomial distributed data, so we talked a little about the binomial distribution and how to find its mean and standard deviation. She was much more comfortable reading a table of Z values this time."
