Recent Tutoring Session Reviews
"We jumped right into our Statistics problems from the moment I sat down. All business here, of course. We walked through variance and standard deviation calculations, as well as the Empirical Rule and other exceptions to the rule. We covered a lot in our session, and I'm sure we'll cover even more next time!"
"We learned how to calculate the Standard Deviation by hand. Step 1: find the mean. Step 2: find the deviation, and then subtract the mean from each X. Step 3: square the deviations (x-mean)^2. Step 4: sum the squared deviations. Step 5: divide by the sample size. Step 6: take the square root."
"We made very great progress on the density function, and I made provided extra practice exercises with a probability set. She was good to work with it, and I look forward to her beyond a constant client."
"We need to practice more, but I saw a lot of improvement in that already today from going through the exercise. The more we use concept, the easier it will become."
"We reviewed a lot of complex mathematical topics such as complex numbers, probability, and averages. I made sure that she understood older Algebra concepts to bring her up to speed on what she's doing today. She feels a lot better with what we've done so far, and I feel like she has done a lot to understand simple statistic concepts with data analysis and dissecting complex information to improve her scores. I can see she is more confident today than where she was before."
"We reviewed a number of quizzes and work examples. A few of the concepts that we spent significant time on were describing data measurements in terms of being interval, ratio, or nominal. We discussed the box and whisker plots, as well as the five data points it features. We talked about the definition of skew, but she has a formula that she will review on her own. We discussed variance and standard deviation but spent more time on comparing empirical rules (z-score) vs Chebyshev's formula. We did a number of examples of Chebyshev calculations."
