Recent Tutoring Session Reviews
"We worked on sample distributions and the student learned how to solve problems like finding the likelihood of a given sample mean given a population distribution and a sample size. We discussed how sample size changes the shape of a sample distribution even while the mean of the sample distribution stays constant, and why this occurs."
"We went over his statistics homework, including z tests, t tests and graphing. We defined multiple terms like standard deviation, nominal data, ratio data, etc. He has homework to look over that we finished. We are going to meet again within the next week or so. No concerns."
"We spent the first half of the session talking about probability and then jumped chapters to the early normal calculations. We were able to get through several examples of each type so the time was productive."
"We spent our time reviewing for the pupil's final exam. We covered how to read a regression table, interpret coefficients, identify statistical significance, and calculate confidence intervals. We then reviewed hypothesis testing. We discussed how to specify null and alternative hypotheses and how to create confidence intervals. Lastly, we went over cross tabulations and how to control for additional factors in a cross tabulation. Overall, he has a good feel for the material and is confident going into the final exam."
"Today we started the new unit and covered hypothesis testing with z tests and t tests. We went over the steps of hypothesis tests, including both the calculations and interpretations. The student is already doing much better with the concepts and calculations of this unit, and has definitely made progress understanding the normal distribution. She was able to complete her homework assignment with no issues."
"Today was a very productive session with the student. We started reviewing the material from chapter 5, specifically binomial random variables and Poisson variables. It is important to get a head start because for the midterm she will be studying a lot of information from the beginning of the semester. Now, we are preparing ahead of time and reviewing the material at the same time she's seeing it in class."
"The student has begun the statistics portion of the course. We simply reviewed some of the terminology of samples. We determined if data was ordinal, nominal or interval. We talked about how graphs can be misleading if drawn a certain way, and the proper way to create histograms."
"We worked on Chapter 19, which included z-statistics, sample size, large-sample confidence intervals,and significance tests drawn from proportions. We only finished about half the problems and intend to meet tomorrow to complete them."
"For this session, the student and I prepared for his exam tomorrow and completed homework assignments. One assignment covered the population and sample mean and deviations using frequencies, which were somewhat more complex than the original formula. He understood the concept. The homework also covered applying standard deviations to conceptual questions and calculations. Finally, homework also covered percentiles (applying them to conceptual questions), z-scores, and interquartile ranges. With some practice of these questions, he picked up the material quickly. He is overall hardworking and an enthusiastic student. He should do well on his exam tomorrow!"
"The student did some general reviewing of the notes she has taken over her class. I believe she had taken adequate notes and has good study strategies and a study friend that she will review with before the exam. She has a good grasp of the basics and should do well."
"The student and I worked on homework problems from his book covering confidence intervals, sample statistics, chi-squared distributions, and hypothesis testing. He seemed to really grasp the material once some of the fog was lifted from the book's explanation of certain principles."
"We went over problems concerning discrete probability distributions for the student's test this week. She felt confident about the material that will be on her test this week. No strategies or study skills were included in this session. I did not leave her with any extra practice."
