Recent Tutoring Session Reviews
"He had a worksheet of confidence interval practice problems. Two problems were with a known population standard deviation, two problems were without, and two problems were finding a required sample size. He has improved a lot in this area and is almost ready for his final. Next session we're going to cover goodness-of-fit for categorical data."
"Student received an A on his latest quiz. We proceeded to prepare for his next test with review of design of study and terminology. We also focused on randomizing sample data and analysis of results. In addition we went over test corrections of last assignment with the addition of chapter vocabulary."
"The student and I worked exclusively on hypothesis testing today. We studied the concepts of creating null and alternate hypotheses, significance level, p-values, and critical values. We completed five different problems encompassing these concepts. She answered them all successfully, and she demonstrated great understanding of when to accept or reject a null hypothesis. She would benefit from more practice finding t statistics, which she can find in her homework assignments."
"We did homework for Chapter 4 of the book. This covered how and why to use r squared, transforming variables using the logarithm function, and regression lines. We used the calculator to find the slope and intercept of the regression line."
"The student and I reviewed discrete and continuous random variables, variance and standard deviation, mean of discrete random variable, drawing probability histograms, discrete probability distribution, E(x) expected value, normal curve, z scores, etc."
"The student and I discussed the concerns he has about his statistics class. We then reviewed a previous assignment and where he went wrong with an eye toward helping him avoid similar mistakes in the future. We then addressed some new material he is working on."
"Today we discussed anova and testing hypotheses about three or more means. The student was very interested in learning what anova was and what was it used for. She solved a few problems pertaining to the subject. I assigned her some problems to do which she will present in our next session."
"We went over problems on her homework that concerned the standard normal distribution, z-scores, and probability. The student seemed to understand the material after doing several practice problems."
"We began by addressing the most difficult problems for her test tomorrow, emphasizing the process and identifying the necessary variables in the problems. We worked backwards through, hitting the pertinent questions."
"The student and I worked on her online platform doing practice and homework. She liked getting help with the homework and extra explanations and I'm happy to help her this way. Her final is coming up so we will meet once more next Tuesday. I believe we should work on compiling a study sheet as well as answering any last questions."
"We continued our discussion of multivariate regression. After reviewing the general concept, we returned to the student's final paper project, which investigates the relationship between poverty and democracy. We explored additional models that take into account the wealth of a nation, health care, education, diversity, inequality, corruption and political instability. In particular, this session helped him in deciding on the final models to include in his paper. We then discussed ways he could outline his paper. Overall, he understands how to approach the project and is getting a good feel how to do multivariate regression in practice."
"Student was able to reschedule her exam for tomorrow, March 13. In preparation, we focused on four topics: frequency tables, z-scores, standard deviation, and correlation. Since her exam is both open note and open book, we created a brief study guide with example problems that she can utilize during the exam. In addition, we discussed the theory behind the problems that we solved. We also discussed hypotheses."
