Recent Tutoring Session Reviews
"The student wanted help with correlation and regression. She had many homework problems, and we worked through them with lots of examples, and we took detailed notes so she'll know how to do it on her own."
"Today was my first session with the student, and I was able to help him out with a few questions he was struggling on. He realized after we covered most of the material that he didn't really have as many questions as he thought he would. We covered Simpson's paradox, least squares regression lines, correlations, and Z-scores, and I gave him a little introduction to what he would be seeing in his probability section of the course."
"Today we reviewed the main concepts that will be covered on the upcoming quiz, like z-score, confidence intervals, and margins of error. We worked on understanding how these concepts fit together. The student will use the notes from this session to put together a 3x5 study notecard with key concepts to use during the quiz."
"Today we spent time reviewing for the quiz the student has tomorrow. We reviewed formulas for confidence intervals and hypothesis test for population means and differences in means, and when to use each formula. We also went over confidence intervals and hypothesis test for the population proportion, including formulas, motivations, and conditions necessary to do inference. We also talked about how we would conduct inference on a difference in proportions, and how those formulas are different and similar to our other formulas. We also talked about the chi-squared tests for goodness of fit and independence, how to calculate the test statistics, how to identify the correct degrees of freedom, and how to find p-values in the table. We worked some confidence interval and hypothesis test problems for a proportion, and we plan to work more practice problems tomorrow."
"Today we studied cases of supply-chain bottlenecks and statistical reasoning to resolve these. Also, the student studied inventory risk management along these lines. Then, I introduced some concepts from probability theory, focusing on conditional probability. Next session, we will dwell on Bayes' Theorem as well as gearing up for the student's final project in this class."
"Today we studied linear regression. When using the calculator to get slope, intercept, r and r^2 these questions were a piece of cake. When calculating these things by hand it was more of a challenge. The best strategy for the student is to carefully compute the homework by hand when asked and practice using the calculator to get answers quickly and accurately for his exam tomorrow."
