Recent Tutoring Session Reviews
"I helped the client prepare for his final exam in statistics. He was given six homework problems and four formulas (standard z-test, z-test for proportions, one sample t-test and chi-square). He didn't know which formula to use for which problem. We went step by step and talked about the decision making process and how to choose a formula. We then worked through three of the formulas. It turned out none of the problems was for the fourth one (chi-square) but I did talk to him about how all of his data was numerical and if he were presented with a problem with categorical data, then he should use the chi-square for that. I also emailed him a handout I've created for chi-square."
"We met for the final time to review for the student's final exam. We went over ANOVA, the confidence interval method for hypothesis tests, chi-squares for goodness-of-fit and independence, and regressions. I think she will do well on her exam if she remembers to study the two different chi-squares and the different equations for regressions. She was one of my favorite students to work with and I'm happy I had the chance to help her. Good luck!!"
"The student and I met today and covered the 1st three chapters of his statistics textbook in preparation for his upcoming exam. We covered basic descriptive statistics. We started with stem and leaf plots. We then moved into measures of central tendency (mean, median, and mode). We both talked about what the differences are between those 3 statistics and worked on their computations. After that, we moved into measures of variability (range, variance, standard deviation, and coefficient of variability), again covering them from a conceptual standpoint as well as how to calculate them. He seemed pretty comfortable with this material. We will get into more challenging material on Friday (elementary probability, binomial probability, normal distribution, and sampling)."
"We covered MANOVA, linear regression, multiple regression, U test, H theory, and some more topics. We decided the student would review the topics in depth on her own and do some practice prior to our next session in order to have a better basis when practicing and discussing. She is on track to pass the class."
"The student and I got started today reviewing some basics of experimental design and sampling strategies, as well as starting on descriptive statistics. So far, he seems to understand my explanations of concepts. Next time, we will get more in-depth with the mathematical aspects of statistics."
"Tonight we went over 15-20 problems in the second chapter of the student's book. We covered frequency distributions and histograms, both creating them and answering more conceptual questions pertaining to data analysis."
