Recent Tutoring Session Reviews
"Today, we went through the student's second lesson on hypothesis testing. Today focused on t-tests. We worked through 2 of her homework problems and referenced her lecture as needed to explain the topic. She does very well with the calculations. I explained that since we do not know the population standard deviation (sigma), only the sample standard deviation(s), we have to use t-tables. I also explained the rules for z versus t in hypothesis testing are exactly the same as for constructing confidence intervals. After that explanation, she understood much better. I explained comparing the test statistic to a critical value to determine whether we reject the null hypothesis or not versus calculating a p value. For her t-tables, it's much easier to compare test statistic to a critical value. She did alright with this topic. I think it will gel for her better when she reworks the problems. We will continue this lesson in our next session, which will expand upon power and also look at sample size estimates."
"The student and I continued to go over her practice test and covered a few new topics: nucleic decay and redox reactions."
"We covered the first 2 chapters in the student's organic chemistry textbook. She understood the material. I left her to work out the end of chapter problems as practice."
