Recent Tutoring Session Reviews
"The student needed help with her computer project for her statistics class. The project had us generating random numbers from a normal distribution. One question even had us generating 10,000 random numbers. We couldn't use her calculator because it would run out of memory. We ended up having to use Excel to do the project. I showed her the code she needed in order to generate the numbers. She was then able to calculate the specified probabilities asked for in the project. Most of the session was just spent getting familiar with the code we would need to generate the needed samples. The only thing left to finish for the project when I left was to write up her procedure and to explain her results. There were also some theoretical probabilities that she needed to calculate in order to compare her results."
"We completed our review of material for the student's final tomorrow. We covered several topics in probability, including continuous and discrete random variables, joint distributions, and calculating the expected value and variance of functions of variables. The student is well prepared for her final."
"The student is preparing for her final exam in Intro to Stats. She's a psych major and has not done very well on her exams so far. She provided a study guide, and she had highlighted the questions she still didn't know. We went over them one by one. They included topics such as how the r values for Pearson's correlation relate to the "best-fitting line," what the regression equation measures, what the different types of correlation are, when and why to use chi-square vs. z-tests vs. t-tests vs. ANOVA, and what exactly we are trying to accomplish through hypothesis testing. After our session, she said she felt much more confident, and she really did seem to understand the material."
"It was nice to meet you today! We got through your study guide pretty quickly, and you understood everything by the end of our session, so I'd say it was a pretty successful session. You pick up on things really quickly so I have no doubt that you'll be able to improve your grade in the class. Good luck on your test tomorrow, and I will see you soon!"
"Tonight we went over material for the second half of the student's class to review for his final exam. We covered histograms, box plots, central tendency, calculating z and t scores, and a number of functions in excel. Overall, I think he has a great handle on the material."
"This was a continuation of yesterday's session. We performed hypothesis testing, and computed many problems with the standard error. The student seemed more confident and had completed many more of the hundreds of sample problems that her instructor had given her. I am confident she will do well!"
