Recent Tutoring Session Reviews
"This student is a graduate student working on a proposal in regards to venture funding. Her goal was to clean up her data such that it would run in SPSS and she wanted to analyze two variables. I discussed with her how to clean up this data best such that SPSS would run smoothly. I also suggested statistical tests that would give her meaningful data."
"I explained expected value, variance definitions, and specific formulas for special cases like geometric, Bernoulli trials, etc. We went over the practice quiz problems, and after doing so, we went back to look at confidence interval definitions and examples. I talked to the student about study techniques: which formulas to memorize, how to approach test questions, and how to interpret what is being asked."
"We spent most of the time going over a few formulas for confidence intervals for proportions. I encouraged her to practice on her calculator habits."
"We covered normal distribution, z-score, mean, probability, and frequency distribution. The student seemed motivated to learn."
"The student is taking an introductory stats class and needed help preparing for an upcoming exam. She provided her study guide and we focused carefully on what her instructor wants her to know. We went over properties of the normal distribution, standardized scores and measures of central tendency so that she understands exactly what the mean, median, mode, and range measure, what variance and standard deviation are, and how to determine scores based on a standardized distribution."
"We began talking about how to apply z scores to answer statistics problems. We started by deriving the basic ideas of sampling distributions from some elementary examples. The student's homework assignment had her computing standard errors from dice rolls and then assigning probabilities to different means. I tried to create a flowchart-type of system for solving these types of problems."
