Recent Tutoring Session Reviews
"The student and I covered hypothesis testing in further detail during our session. We went over how to set up various null and alternative hypotheses. We also reviewed how to find test statistics for these various tests. Lastly, we covered how to use the test statistics to determine a conclusion about our null hypothesis. He has a worksheet he will be working on in the next few days for class about the material we covered. I will review this homework with him during our next session. I thought he had a really good understanding of how hypothesis tests work."
"Today the student was struggling with calculating means and standard deviations for frequency distributions, so we went over these formulas and practiced using Excel and a calculator to compute these values. We also looked at box and whisker plots, skewed data, and the five number summary. We reviewed z-scores and how to compare two data points based on their z-scores. She just got her last assessment back and earned a 94. We celebrated by doing more math! I have begun giving her less support in the form of notes and more in the form of short, guiding questions and training her to ask these questions of herself when completing problems. She is developing her statistical reasoning skills and is becoming a strong reasoner and statistician."
"We reviewed a few PowerPoints from the student's lectures on chapter 9 and chapter 10 to help her study for her test tomorrow. I think that it helped her get a firm basis of the material and pointed her in the right direction to study for her exam."
"We went over more practice problems to prepare for the student's exam tomorrow. Problems covered identifying independent and dependent variables, calculating z-scores, interpreting standard deviation and p-values, and chi-square tests."
"Tonight we reviewed for the student's first statistics exam. He took stats in high school and seems to understand all the material he has covered to this point very well."
"We discussed how to find the individual probabilities, the expected value, and the standard deviation for a probability distribution. We used a table to find the different values, and the student appeared to understand how to get from one column in the table to another. It is also important that she remembers the sum of the 3rd column is the expected value and the square root of the sum of the 6th column is the standard deviation. There were a few issues with rounding and a small mistake with one of the probabilities, but I sent her corrected values to use in her homework."
