Recent Tutoring Session Reviews
"T-scores and tests, standard deviation of a sample, and determining whether to reject when there is no effect in a sample."
"The student brought along a college math placement assignment to be completed before the start of spring break. I have advised him to complete the packet independently, showing all work for every problem, even though the assignment is multiple choice, and to come to me with questions and clarifications next Tuesday. Due to the nature of the assignment, I've decided to let him attempt it for the most part in order to yield a true picture of where he stands on the concepts covered in the assignment. We reviewed the normal distribution and I added more depth by exposing the student to the division of probabilities beneath the curve. We also reviewed standard notation for the normal distribution. He also seems to be reaching a better visceral understanding of how accurate notation is important/helpful. New material for today was the Central Limit Theorem and topics in sampling variability, including variability of sample means. I will be revisiting the Central Limit Theorem in more detail with the student when his class arrives at that chapter. Going forward, I will aim to stay 4 chapters ahead of the current topic(s) in class, but no further."
"The student and I covered the introductory chapter of his textbook, which included an introduction to using mathematical models to help inform decision making."
"The client is taking an introductory statistics course and wanted help understanding her weekly assignment, which was on choosing an appropriate hypothesis test based on a specific research question. We went through all of the options, including z-tests, t-tests and ANOVA, and why or why not these tests were a good choice for the question."
"Today we looked over radians and degrees for polar angles. We discussed how to convert them, how to find reference angles, and how to determine coterminal angles. Everything went really well, and I think the student already has a solid foundation for this material. He'll master it with just a little more practice! We'll meet next at our regular Tuesday time. Thanks!"
"The student wanted to focus on reviewing for her statistics class tonight. She had some questions on terminology and definitions, then asked for examples of permutation calculations. I explained her lecture slides and went over some basic examples. Then we talked about parameters vs. statistics and different types of charts for displaying data. She said she needs to learn how to use Excel for data analysis. I set up a shared Excel file so we could both work together on entering and graphing some data. Using numbers from one of her example problems, we made a histogram, and I explained the steps required. She is finishing up her classes this week, and we scheduled our final two sessions for next Wednesday and the following Sunday to finish preparing her for the final."
