Recent Tutoring Session Reviews
"The student is studying for her final. She has a final review. Today we covered basic statistics (mean, SD, etc.), regression concepts, and basic probability. These concepts were at the beginning of the class, so we are doing a lot of reviewing. There's a lot to remember. She has been working the practice exam and writing down the steps on a notecard to help her remember. We are having one more session tomorrow to finish off the studying. The beginning of the course is the area we need to focus on the most because it has been so long since we worked on that stuff."
"The student continues to have a strong grasp of the material, particularly hypothesis testing and confidence intervals, which often baffle students in introductory courses. She has the mechanics of the problems down cold. To my mind, the (slight) weaknesses in her understanding relate mostly to her interpretation of the null vs. alternative hypothesis and to conditional probability, which she describes as her "white whale." We have two more sessions remaining, and will focus on shoring up her knowledge and review in order to make sure she hasn't got any problems."
"We covered Bernoulli trials and the geometric, binomial, and normal models. The student had a little trouble understanding binomial models on the calculator and the difference between binomial pdf and binomial cdf, but she seemed to have a good understanding after we did enough problems."
"The student informed me that she had a quiz this Thursday. We went over her Chapter 5.2 homework, and I gave a preview into 5.3. Also, she went over the old materials to prepare for a make-up quiz."
"We went over the student's extra credit assignment on z-scores and normal distributions. There were three types of problems: 1) Using z scores to determine the probability of obtaining a certain x. This can either be written as a word problem or in mathematical format of P(x
"Today, the student and I continued working with linear regression for binary response variables. We covered the general procedure to create a probability curve based on the explanatory variable and how to test the accuracy of a model. We also went over the diagnostic tests required to ensure our model is valid."
