Recent Tutoring Session Reviews
"Today we went over the two types of calculating probabilities; Classical and empirical methods. We then reviewed the concepts on disjoint/mutually exclusive events, and dependent events, and how to calculate the difference between those two. We also reviewed complimentary probabilities, and how to calculate the likelihood of two events occurring. We went over several examples which required him to choose which method to use for the calculations. Overall the session went well."
"Today we covered types of distributions (sampling distributions, normal versus binomial/Poisson distributions), standard error, z-scores (both conceptually and how to calculate them), and how to find the probabilities of scores on the normal distribution. We also reviewed the resources provided by the student's course. We made good progress in figuring out how best to approach the course, which includes reviewing the course lectures together then working on the problem sets."
"Finished on statistical testing and confidence intervals. The student is much improved on identifying and conducting the tests and intervals. He can improve on remembering certain vocabulary (type 1 error, type 2 error, etc.). Has a test on Monday (7/28)."
"The student has finally reached the point in the semester where they are covering hypothesis testing. This is helpful for her, as it shows the reason for learning all of these techniques. We discussed how each of the problems were really just dressed up versions of previous homework assignments, and she was able to convert the information into our usual parameters and work with it easily. She seems to understand what t and z tests are for, though she sometimes needs guidance to find the right information to put into the right equations. I was able to guide her through her homework so that she was able to complete the rest of the assignment on her own. She should study this information extensively, as her final exam is likely to be focused on application problems."
"For this session, we covered topics in hypothesis testing for both population and sample. We worked and discussed each question from a quiz on the subject, making sure each was as clear as possible before moving on."
"The student and I continued on with the chapter on standard normal curve. Today we focused on calculating z-scores to use in determining the percentage of scores within a specific range of scores. We also went over how that relates to figuring out the probability of getting a score within such a range. The use of the standard normal table can be confusing for students so we spent some time going over that aspect of the material."
