Recent Tutoring Session Reviews
"In this session, we focused on calculating expected values, standard deviation, variance of a random variable when adding or multiplying by a constant. We also reviewed various topics prior to her exam tomorrow including using the binomial table when n = 15."
"The student requested that we begin reviewing for his two-part stats test coming up this week, so we started by discussing various vocab, objectives and concepts he needed clarification on from his review guide; I also provided him examples when possible and encouraged him to do the same. We reviewed the following: levels of measurement (i.e., nominal, ordinal, interval, ratio), confounding vs. lurking variables, various samples vs. various sampling techniques, experimental vs. observational designs, and randomized block designs vs. matched pairs. He was able to differentiate among frame vs. seed and retrospective vs. prospective studies. Although he seemed to have a good grasp after our discussion, I encouraged him to review the types of samples (e.g., stratified, systematic) and his prior homework. He was attentive and cooperative throughout the session."
"The student was focused. They had a question from statistics and lots of questions involving vectors and math. I addressed the statistics question, and we discussed the key terms they would need to use for their request for help in math."
"The student worked on a bit of both statistics and algebra review for statistics. The first concept was r, the linear correlation coefficient. To his credit, he learned quickly how to use it and have it crunch the numbers. The next set of problems was interpreting the slope-intercept form of the line equation. He had some struggle with converting a standard form equation (Ax+By=C) into the slope-intercept (y=mx+b) format. He kept trying to get to a single solution, and "overthink" the problem. I will come up with some good step by step examples to show that all we're doing here is manipulating the equation to look a certain way but still be the same equation."
"The student worked through the correlations very well. With the extra work and time spent, she will do great on her quiz tomorrow! She does a great job of understanding what each statistic means and can figure out how to solve the problems. I will be sure to do my homework on RStudio so we can talk about that next time if needed."
"The student's attitude was energetic and eager to learn. The student struggled the most with the proportions related to the two-by-two tables, but we figured it out and the online portal with the math whiteboard was helpful. We employed solid strategies for understanding the basic mentalities towards statistics problems, like determining if experimental or observational problem"
