Recent Tutoring Session Reviews
"We covered the concepts of explanatory and response variables, the correlation coefficient r, the properties of the correlation coefficient, regression lines, least-squares regression lines, residuals, predictions based on the regression line equation, influential vs. outlier points, categorical variables, marginal vs. conditional distributions, extrapolation, and noting the distinctions between associations and causation. I explained each of these concepts according to the slides from the student's course. We will cover materials from CH. 3 in our session tomorrow."
"We did a comprehensive review of the material covered since the student's last test. I made a practice test for him in preparation for his exam tomorrow. The student shows that he has mastered the basics of confidence intervals and hypothesis testing. He still has some trouble with word problems. I gave him several examples to work from, but I believe that the main issue is that when confronted with a complex problem, he freezes. This is likely the result of test anxiety, which he has said he has problems with. I gave him several methods that should help alleviate this."
"We finished reviewing the student's Ch. 9 and Ch. 10 quizzes. She made great progress on understanding hypothesis testing, confidence intervals for a mean and for a difference, and simple linear regression. By the end of the day, she had met her goal of passing this statistics class and fulfilling her math requirement for her degree."
"We finished up reviewing the lesson material for the student's upcoming midterm, including sample mean calculations, standard error calculations, and introduction to the t-distribution. We then made a formula and review sheet for her midterm and covered examples of different calculations. We also reviewed vocabulary and conceptual ideas by quizzing. I believe that she has a good grasp on the concepts and formula. I recommended that she review her quizzes and homework again before her exam tomorrow. Overall, it was a great session and I felt confident that the student had a much better grasp on the material than when we first began."
"We focused on computing hypothesis tests and confidence intervals for paired data, doing inference about a difference in means, and using the t-distribution. We went over interpreting these intervals in context, the definition of p-values, and why rejecting the null hypothesis is not the same as accepting it as false. We also talked about the conditions that are necessary to conduct a paired-data hypothesis test."
"We had a great first meeting today. We worked through some concepts that the student's professor had gone over too fast, which included setting up frequency tables, variance, and some small parts about central tendency. We also covered distribution shapes a bit, specifically in terms of standard deviations and variance."
