Recent Tutoring Session Reviews
"The student and I had a good first session. We got through all of the review problems he had for his final, so tomorrow we are going to look at some problems I provide."
"We reviewed the midterm exam the student took about 2 months ago. She had some questions regarding expectation values of unusual parameters, like sum of rolls and minimal values in a set. We focused on the brute force approach for most of those questions."
"This was one of the best tutorial sessions I've had in a long time. The student moved forward in the textbook, further into the section on determining the necessary sample size in order to compare the means of two populations at a certain level of confidence. He had some questions on this material, which we reviewed conceptually. He also did the next section, which contained some fascinating ideas that I hadn't learned -- on the F-statistic -- which is part of the book's newest edition curriculum. We studied this material together and looked at the problems he had done on them. One part of these problems required us to calculate p-values, which he emailed me notes about. He really has a great mind for statistics, and despite making the occasional beginner's errors (misreading equations or arithmetic), he grasps the subject very quickly. At the end of the lesson, we looked at how Excel can be used to find best fit lines, and display their equations and R-squared values. At our next lesson, we'll move into the F-statistic more and also into p-values, and I'll hand back his chapter 7 homework."
"We worked on hypothesis testing and confidence intervals. I mostly invented problems and the student was able to solve basically everything. We did proportions and two- and one-tailed tests. We get into means and t-score next time."
"We reviewed the three types of distributions we've learned about already: Binomial, standard normal and the sampling distribution of the mean. I also talked about using the standard normal distribution to find probabilities associated with proportions."
"The student and I continued to work on both Z and T scores. We solved problems related to one- and two-sample statistics. With respect to the problems with two samples, we talked about the various assumptions (i.e. independence) and what to do when they might be violated. This included a discussion of the repeated measures and matched responses procedures. In addition, I answered her questions regarding her upcoming paper assignment."
