Recent Tutoring Session Reviews
"During our session, I helped the student work through problems on his homework for Section 11.5. These questions covered hypothesis testing, test statistics (both for t-distributions and z-distributions), and p-values. He had a good grasp on the hypothesis testing."
"During this session, we first reviewed the nature of quantitative variables versus categorical variables. The student then constructed dot plots, box plots, and histograms of quantitative data. We discussed how adding extreme scores to a distribution affects the measures of central tendency and variability of the distribution. We also discussed the basic concepts underlying correlation and regression including interpretation of scatter plots relative to the magnitude of the correlation coefficient."
"I covered the normal distribution, survey sampling, and confidence intervals. I helped the student work through some practice problems. He was behind in his class and needed help understanding the concepts, especially z scores and reading the normal table. We will continue to work on this next session."
"I helped the student prepare for her final exam, going over problems involving confidence intervals and hypothesis testing of means, proportions, and their differences. Overall, I expect she should do well on her final."
"I helped the student review for her statistics final by covering the binomial distribution and how to solve binomial problems, the normal distribution, z-scores, and creating confidence intervals for both proportions and sample means."
"I introduced the student to the ideas behind control chart and showed him some with dummy numbers that I made up. I supervised him as he did the charts in Excel with the data he had and corrected errors as he made them."
