Recent Tutoring Session Reviews
"The student wanted help with introductory statistics. We discussed properties of the normal distribution; measures of central tendency; and other concepts, such as the difference between experiments and observational studies and correlation and causation. We also constructed frequency distributions and interpreted them."
"Today, I discussed a few more basic statistics concepts with the student. We went over how to solve hypotheses tests with one population standard deviation and two population standard deviations. This dealt with using the chi-square statistic and also the F-statistic. We then finished with talking about population proportions and performing hypotheses tests with one and two population proportions. We will continue to talk about population proportions and finding the confidence interval for them on Wednesday."
"Today, we did a practice exam. It went well, but tomorrow, we are going to revisit questions that were easy once we knew what to do but were tricky to get started. When we revisit them, I won't give hints on what to do. The student figure them out on his own."
"Today, we finished simple regressions and started to discuss strategies for the exam. The student should thoroughly review her regression notes in advance of tomorrow's session on multiple regressions."
"Today, we focused more on the Z-score. We mostly did two types of problems: converting from a data value to a probability and converting from a probability to a data value. We also covered the central limit theorem."
"Today, we talked about the description of data using numerical measures. This included the mean, median, mode, range, IQR, boxplots, variance, and standard deviation for both a population and a sample."
