Recent Tutoring Session Reviews
"The student is an extremely motivated student who was struggling with some of the concepts of statistics as it relates to psychology. We covered a very broad spread of topics, such as what standard deviation means and how to calculate it. We also discussed the margin of error and what is needed to do that calculation. She also wanted me to clarify some of the different types of validity, such as content and construct validity. We also discussed the difference between incidence and prevalence. Lastly, we touched on how to calculate the consumer price index. She was extremely quick to pick up the concepts and motivated to learn them. I felt that she was a lot more comfortable with the material after our session."
"The student's next homework is on population parameter estimation from samples, and chi-squared tests. I went over the concepts and we worked through most of the problems. The material is very new to her, so it is a lot to learn at once, but I think with practice she will catch on quickly. For Sunday's session she will finish the homework but we will also focus on the expected value and other topics that should be on the review sheet. I will provide her additional textbook example problems as need to help with learning the concepts."
"The student needed help with t-tests. She had two problems. One involved a two-sample t-test and the other a one-sample, matched pairs t-test. Confidence intervals were also asked to be calculated. The instructions required the student to write out statistical formulas using Microsoft Word and this is what she needed the most help with. She was great with the calculations. I gave her some tips on using her calculator to get them done faster. I also helped her interpret the p-values for each of the t-tests. She is doing great in her class. She scored a 91% on her last test."
"During this session, we focused on tests of significance. We talked about establishing conditions and hypotheses, and did hand-calculations of z-score and p-value on one problem. We also talked about how to tell if confidence intervals and tests of significance are consistent with each other."
"Tonight we reviewed for the student's second exam which is covering multiple regression analysis. We went over a few calculations, going over how to use the t table for critical values, key terms like multicollinearity and heteroscedasticity, and interpreting ANOVA output."
"The student has a test this coming week. She had a review that had many problems cut and pasted from different sources. Each one was multiple choice and she had tried some of them on her own. We went over each problem, even the ones she had tried. She got all of those correct. I also showed her ways to do most of the problems with her calculator. At the end, I made some similar problems and had her try those herself."
