Recent Tutoring Session Reviews
"The student and I continued working through homework for her course in introductory statistics using SPSS. We had a new dataset, research questions and hypotheses and we input the data, ran the analysis, and generated tables in the format wanted by her instructor."
"The student and I reviewed for her exam. We tested hypotheses of normally distributed and binomial samples, using the formula and using programmable calculator functions. We calculated minimum sample size to produce a given margin of error for normal and binomial samples. Finally, we formed confidence intervals using the formula and calculator programming."
"The student and I reviewed hypothesis tests and using the p-value approach to reject or not reject null hypotheses. She was increasingly confident, both in using her graphing calculator as a tool and in manually computing the p-values. She initially struggled with finding areas under the curve for positive z-values but showed improvement over the session. She was able to find the area under the curve and then determine whether or not to double that area depending upon the tails of the test. We also began discussing her crib sheet for the final exam and any older concepts she needed to review before her final. We will review the critical value approach in our next session, which will be the final new concept to cover."
"The student and I reviewed lesson 9 for her statistics class, which included two independent proportions t test, two independent means t test, and a paired t test. She seemed to have a good understanding of which situations to apply each test to, hypothesis testing, and analyzing the results of the t test. I think one area that could be strengthened a bit is determining the correct null/alternative hypothesis for a given study. We created summary sheets for each of the bigger concepts for her to use to study later. Her quiz and homework scores to date have been improving, and she was happy with the score on her last exam."
"The student and I reviewed the practice questions provided by his professor to help him practice for his SPSS/Statistics final. We practiced one sample T tests, 2 sample T tests, an ANOVA, and chi-squared. I also helped him answer questions in the format that his professor is picky about. We also went over how to calculate Eta squared, and I showed him a trick for SPSS to generate that metric."
"The student and I spent the session continuing to review for his final. We briefly returned to trig and the unit circle to ensure he had those concepts down pat. Then, we moved on to graphing. We began by going over how to graph trig functions, looking at the basic sine and cosine functions and how each of the four major function transformations looked on them. Then, we practiced a couple of sketches. We ended the session by thoroughly reviewing the process on how to sketch polynomials. We especially focused on the roots of the polynomials, how to plot those roots based on whether they were in the numerator or denominator, and the "end-function" behavior. I covered the three major conditions for end function behavior and how they turn into horizontal asymptotes or go to an infinity."
