Recent Tutoring Session Reviews
"We reviewed for her exam tomorrow, covering how to calculate the correlation coefficient, standard deviation, variance, z-score, and observation point. I emphasized the point of how to find the probability in the table and find the z-score."
"We reviewed for the unit test. The student defined and contrasted correlation, correlation coefficient, regression, coefficient of determination, coefficient of nondetermination. He also Identified the components of a regression. He tested the significance of given Pearson correlation coefficient as well as tested goodness-of-fit with Chi-squared distribution."
"We reviewed practice problems involving relative frequency, cumulative frequency, stem and leaf plots, histograms, bar graphs, qualitative variables, independent vs. dependent variables, and box plots."
"We reviewed problems in preparation for an upcoming quiz. The topics included sampling distributions, central limit theorem, and probabilities. The student had difficulty with the material, but as we worked through the problems, she was able to articulate the approach to the solutions."
"We reviewed the geometric distribution function, probability density function, expected value, and the Bayesian formula. The student struggled with formulas that involved using a sigma the most. He was positive and confident throughout the lesson. He is going to ace this final!"
"We reviewed the homework problems that included the use of formulas and calculations for binomial probabilities. After completing two different sample problems, we worked on how to use the mean to calculate an expected value. Lastly, we reviewed calculating a z score and using that to establish a probability of a value greater than, less than, or between two x values."
