Recent Tutoring Session Reviews
"In this session, we reviewed hypothesis testing on a mean when the sample size is small (t-statistic), including one-tailed and two-tailed tests. We also covered hypothesis testing involving a proportion (z-statistic), including one-tailed and two-tailed tests. We identified null and alternative hypotheses, critical values, calculated test statistics, and interpreted results. We scheduled another session for tomorrow afternoon to continue where we left off, which will be with hypothesis testing involving two independent means."
"The student's final exam is tomorrow, so today was mostly review. We went over two of the student's past exams, which covered probability and confidence intervals. I provided her with extra practice midterms and a sample final as well as the solutions. I am confident that she will do well on the final."
"This session was focused on his final project. I helped the student review interpreting the min, max, median, and 1st and 3rd quartiles in terms of his problem. I showed him how to quickly turn those numbers into a boxplot. I helped him calculate the IQR and detect for potential outliers using IQR. We found no potential outliers in his sample data; however, the shape of his data's distribution is not normal. I tried to explain how this could be potentially hazardous to completing steps later on in the project so he said he will ask his professor about it."
"This session we covered correlation, looking at r values, predicting values based on a regression equation, and r squared values. The student had some trouble understanding methodology at first, but grasped the concepts towards the end of our session. The student has a good attitude overall, as she knows the end of the course is near and is looking forward to being done. Overall, progress is steady and the student should be well prepared for the final exam."
"This session, we covered two sample hypothesis testings. This included tests with pooled variance, bootstrap testing, tests of two proportions, and the use of R to perform these tasks. I think this student has developed a pretty good general understanding of hypothesis testing, and all that remains for the rest of the semester is practice with correctly applying the right hypothesis test."
"This was our final session. The student appeared to be more confident in her abilities. She has made great progress in understanding the topics that will be needed for her final exam. She is more accurate with her manipulation of data for main and interaction effects. She also is accurate with determining and understanding regression lines. She has greater difficulty with understanding ANOVAs. She benefits from practice problems and from the tutor working side by side to identify a mistake."
