Recent Tutoring Session Reviews
"Worked on another previous assessment exam. Topics included standard deviation and mean of a data set, correlation coefficient for linear regression equations, imaginary numbers and simplifying into a + bi form, using the double angle trig formulas to solve equations, etc."
"Today we worked with conditional distributions, marginal distributions, and contingency tables. The student found this to be a lot of fun because we didn't have to use Excel or Minitab. We discussed how the wording of questions is very specific and takes great care with this aspect of statistics. We also discussed her graduate research. What factors is she interested in testing? What factors will influence this but are not actually of interest? Will she be able to get a large enough sample to account for these lurking factors or should she instead narrow the scope of her research to better isolate the factor of interest within just one of the lurking factors?"
"We reviewed concepts in preparation for the student's final examination. We went over information regarding polar coordinates and differential equations."
"The student and I continued working on the review package for her final exam. We developed polynomial functions given the intercepts and their multiplicities. We also worked on the graphs of parabolas. We worked with the various forms of the equation for a parabola."
"The student and I worked on combinations and permutations. This is a tough topic and she did struggle a bit when trying to decide if order mattered or not. By the end of the session, she was able to identify the difference between permutation and combination and their formulas. I did leave her with some extra practice (worksheets and a website)."
"We covered quadratic equations, solving using either factoring, isolating the square, or using the quadratic formula. We have solved equations like this in the past by factoring, but the use of the quadratic formula was new. The hardest part is simply memorizing the formula, the student seemed to already know how to write the formula and apply it to a given equation. We mostly worked on the simplification of the expression obtained, and how to use the expression to write the two real-valued solutions."
