Recent Tutoring Session Reviews
"Today, I worked with the student on reviewing finding the probability of a type II error and also figuring out what beta and power mean. I then started talking about hypothesis test dealing with two population means. We discussed using a pooled standard deviation when the population standard deviations are the same and a non-pooled statistic when the population standard deviations are different. On Friday, we will talk about when we have paired samples using two populations and then get into one population situations and proportions."
"Today, we worked on covering some concepts from Chapters 6 and 7 in preparation for the student's exam on Thursday. We looked at matched pairs t procedures, finding the t value, finding the P-value, and determining when to use Z-score vs. the t-test."
"Today, we worked on discrete and continuous distributions. We discussed how measurements like weight and length are continuous because you can always find a more and more accurate ruler. Two discrete probability distributions that we worked with were binomial and poisson. When we meet tomorrow, we are going to study for the student's test. He was not pleased with his grade on his last test, so we will try different study techniques this time. Hopefully, we can look over his last test and let that inspire our study habits."
"We began by discussing the student's lab due tomorrow, and then spent the rest of the time going over a few chapters in his textbook. It appears that he is comfortable with basic definitions, but likes to know how things are derived and needs some guidance putting the pieces together. I did my best to show him how everything is connected and why these concepts are important to the study of statistics. As soon as I explained where everything comes from and the distinctions between certain definitions, he seemed a lot more at ease with the material, and seem gratified that it all made more sense. I look forward to working with him again as his assignments and topics get more advanced!"
"We continued to go over the student's project and descriptive statistical techniques (box plots, ANOVA tests, descriptive tables). She would like to know how to interpret descriptive and inferential statistics to meet the project goals. We looked into process-control statistics and graphs and would like to continue going over those later. She had a positive attitude and felt good about the material. We merged two data sets and learned how to use Excel to clean tables to make them look nice. She is making great progress for her upcoming presentation."
"We continued to work on the portfolio that is due Sunday, and looked at the ANOVA test and conclusions section the most. Waiting on some responses from the professor, we are looking to meet on Saturday to prepare for the end of writing the portfolio and making sure the tests are all done right and the written sections are looking good."
