Recent Tutoring Session Reviews
"The student and I had a very constructive discussion today. He has a test next week that will cover decision analysis, time series forecasting, and one-way ANOVA. We started working through a document with 9 review problems on the material to be covered in the current unit, and we completed 3 of them. The subjects included expected value, probability, payoffs, decision criteria, regret calculations, decision trees, and risk profiles."
"We did one practice problem about how to calculate differences in consumer and producer surplus before and after a tariff. I described one method of visualizing these changes by drawing the supply and demand graph with the old and new prices then labeling each of the relevant areas with letters. We also discussed how this method could be used to calculate government revenue after a tariff and deadweight loss. Finally, we reviewed one of the old practice midterm problems, discussing the difference between a tariff and quota (voluntary export restraint)."
"The student and I worked through his homework from Econometrics today. We made some good headway, and he was eventually on a trajectory to finish his homework before the start of class this afternoon."
"We reviewed material in preparation for the student's final exam. The problems covered hypothesis testing for means and proportions and type I and type II errors. The student had some questions about when to use which formula, but at the end, she was more confident in her understanding of the material."
"For today's tutoring session, we reviewed the PowerPoint that the student emailed me. It was on predicted values of Y which she mentioned that her professor did not go over in class. For this section, the big difference is that this is strictly finding the predicted y component. We reviewed finding the confidence interval and predicted intervals for the y, and it is important to know that the formulas and interpretations are different. Additionally, we reviewed the problems regarding to linear regression. I advised her to review the PowerPoints since her professor did not go over them in class."
"Today we covered a few topics that will be on the student's upcoming exam. These topics were confidence intervals for means, working with exponential distributions, and working with sampling distributions that involved proportions."
