Recent Tutoring Session Reviews
"In this session, we covered the binomial distribution and using MS Excel to obtain the cumulative probabilities for a binomial distribution. We also covered using the standard normal distribution in two different ways. One was if z was given and area above or below was needed or the area between two z values. The other approach was when area was given, and we needed to identify the z value."
"The student and I reviewed more practice problems for his exam. This session focused on z-scores, applications of the normal distribution, and uniform distributions. He needed a little reminding on the concepts that were a little older, but once we worked out a practice problem together he was able to do many more on his own with very little guidance from me. He is doing great, and he is learning how to use his calculator in order to save himself some time on many of these questions."
"The student and I went over some homework for her statistics class involving chi-squared tests. We discussed the difference between Goodness-of-Fit tests and tests for independence of two factors. We examined the methods of computation for the chi-squared statistic and the appropriate degrees of freedom for each. The student learned to do the computations on a TI-84 calculator."
"The student and I went through a brief introduction to the nature of statistics. Mostly, we discussed sampling, sampling methods, controls, and margin of error. We only touched on qualitative analysis, but the quantitative aspects should be coming soon!"
"The student and I worked on a review for her test that is tomorrow. We focused mainly on Chapter 6 and then went into Chapter 7. Chapter 6 had to do with focusing on finding the confidence interval and the margin of error. She was able to learn how to work through it. Chapter 7 was focused on solving for the hypothesis. We solved one problem from that chapter. She remained focused throughout the entire session and reported that she would utilize the math lab in school to assist her in studying and learning more about the Chapter 7 test."
"Today was a review of more ratio and rate problems. Whenever I used physical or familiar examples, such as the ratio of one type of coin in my pocket to another, or dollars per hour for rates, he could answer any question I threw at him, but as soon as we went back to his homework assignment and started working in kilometers per hour or the ratio of roses to lilies in a bouquet, he had lots of trouble. He is most definitely a visual, hands-on learner. I try to help him "convert" his homework problems into more familiar scenarios with the same numbers, and that sometimes works, but I need to come up with a way that he can do it on his own. We went over working with and converting units, as well as how to deal with fraction within fractions. He should remember the techniques we used on all of the ratio problems for his test this week."
