Recent Tutoring Session Reviews
"We reviewed the student's homework and covered normal distributions and binomial probabilities. We discussed how to use his calculator instead of the Z table which he found cumbersome and also how to use his calculator for the binomial probability problems. He seems to have a firm grasp of the material, and for the most part we just clarified small distinctions in some of his notes."
"We spent this last session working on goodness of fit testing, including setting them up, entering them into calculator, and making assumptions based on result. We also reviewed notes to ensure the student has everything she needs going into her final exam on Thursday."
"We started by going over one way ANOVAs by doing one by hand with baseball data I provided. We did this by hand to break down the process, and have her get more familiar with computing sum of squares and mean squares. I provided baseball data for a two way ANOVA to be done by hand, and she decided to do it as homework. We ended by quizzing her on vocabulary from the end of the chapter."
"We started the next unit in the course, which is about producing data. The two components of this are sampling and study design, and we began with sampling. We went through several ways of sampling: volunteer samples, convenience samples, simple random samples, cluster sampling, stratified sampling, and multistage sampling. Volunteer samples and convenience samples are likely to have bias. Simple random samples are better. We then worked through a StatCrunch activity that involved looking both at a random and a nonrandom sample of a dataset. The random sample was representative of the population for all the variables, whereas the nonrandom sample was not."
"We talked mostly about discrete random variables and discrete probability distributions. The student came into the session not being able to conceptualize the definitions or really understanding how the equations work, but after discussing these ideas, I think he feels a lot better about the material. He clearly just wants to understand the material and I think he finds it cool and interesting once he actually comprehends it. We also spent some time going over problems together. He is doing extremely well!"
"We went over a handout the student needed to complete for US history. While talking through the chapter, I talked to him about the various readings as we went through them. I believe organization will be crucial to his academic success, so I plan to push him to take notes on the various subjects that we'll go over so he'll be able to study more effectively. Hopefully, we'll have more to go over next time we meet!"
