Recent Tutoring Session Reviews
"During our session, we went over some of the questions on her midterm that she missed. These questions covered defining observations, choosing the appropriate visualizations for data, determining outliers, understanding a histogram, and applying the central limit theorem to highly skewed distributions. We then worked on starting the exercise for the next unit of her class, which covers t-statistics. We first went over when to use the z-score vs. t-test, what bootstrapping is used for, and how to calculate the t-score. We also went through how to identify the parameter of interest, the point estimate, and null vs. alternative hypothesis."
"I covered the basics of probability theory, including probability mass and density functions, variance, expectation, and standard deviation. I helped the student work through a practice quiz. She was able to grasp the material adequately, despite having little math background."
"In this session, we covered basic probability. The student had various problems that related to conditional probability, joint probability, and marginal probabilities. We also worked on a few 2x2 and a 2x3 contingency tables that required that we calculate the joint probabilities, marginal probabilities, and/or conditional probabilities. I offered suggestions and tips regarding how to approach some problems. For example, be careful with the conditional probability and ensure that the denominator is the correction marginal probability. We also covered how to demonstrate independence and how to demonstrate if events are mutually exclusive. He will contact me to schedule another session."
"Nice session with him on statistics by R programming. The homework data analysis problems are quite easy to solve, but the R syntax details and debugging is a little time-consuming. We just need a little patience and careful coding in the windows. Overall, it's good!"
"Review of t-statistic for linear regression correlation coefficient significance assessment, ANOVA and the f-statistic, and a few review questions on when to use what statistical test based on properties of the given data."
"She and I covered mainly standard deviation and mean as that was the focus of her homework. At first, she seemed to be struggling with the concept of standard deviation and being able to visualize what a standard deviation is and what it looks like. Towards the end of our session however, she seemed to be getting the concept much more quickly. I feel that the conceptual questions are much harder for her than the ones where she simply has to do calculations, even when those calculations must be done by hand. She has a busy week coming up with extra curricular activities, so we are going to get together on Sunday to review before her exam on Monday. She is going to have an exam review packet that we are going to go over together. Her goal is to score higher on the next test than she did on the first (she had about a 75% on that test)."
