Recent Tutoring Session Reviews
"Today we worked on the student's project, which she is mostly done with. We then reviewed for her test by making a study sheet for helping her determine the appropriate Chi-square test to use. We then practiced a few Chi-square problems."
"This session focused on the meaning behind accepting and rejecting null hypothesis. Specifically, we determined what is alpha and what is beta."
"We did linear regression by hand (using a calculator), finding y = aX + b. We also found the confidence interval for b, did a two-sided hypothesis test for b, and discussed the meaning of positive and negative correlation."
"This was my last session with the student for the semester. We reviewed chapters 6 and some of 5 for his final - that would be binomial and continuous random variables, geometric random variables, and unions versus intersections."
"We covered the student's exam which is on Friday. She was struggling with interpreting coefficients. She was grasping the concepts more easily. She will be working on the practice test."
"We went over the criteria for selecting independent vs dependent (possibly correlative) data sets to determine the type of test to perform in order to determine the probability that sampling results accurately reflect what is true of an entire population at a given level of significance. We solved several problems of different types of t-tests. The major take-aways from the lesson were: 1) be careful when using the calculator; 2) if two data sets used different and unrelated populations, the test used should be for independent populations; 3) be careful about the degrees of freedom applied to each test. She was very quick to catch on to concepts, has a very positive attitude, and promised to let me know how she does on the final exam tomorrow. She seemed very pleased with the session."
