Recent Tutoring Session Reviews
"Today we worked through a homework assignment on the relationship between z-scores and percentiles. This involved introducing the student to the z-score chart. Since we spent so much time building him up a foundational understanding of standard variation, today we sort of a breeze, and the student clearly feels pretty confident right now."
"The student's exam is tonight and so we went over the last chapter she needed to study to prepare for it. We covered a number of different topics related to null hypothesis significance testing. At first, the student found the material confusing (as do most students!) but as the session went on, she gained a clear understanding of what the null and alternative hypotheses are and how we determine whether or not to reject the null. We also focused on the way to determine if the test is one or two tailed and how to find the rejection region."
"We reviewed the student's test and started probability. She only scored 60% on her test, although this was the average score--her teacher does not grade on a curve. She can do much better if she keeps up with her homework instead of saving it for the few days before a test."
"We covered one way between group ANOVA, correlation coefficient calculations, different ways of calculating effect size, interpreting a scatter plot, and figuring out if a correlation is significant using the t distribution. The student has put a lot of work into the material. The student is finishing up the course next week and if she needs any help with her final project she will contact me."
"We went over problems on her statistics HW that covered various concepts of probability such as the binomial distribution and the hypergeometric distribution. No strategies or study skills were included in this session. I did not leave her with any extra practice. No scores or grades were shown to note progress. I have no concerns or wins from this session."
"In our first session, I tried to familiarize myself with the student's learning habits, for how best to use our sessions productively. We covered two homework assignments, and discussed concepts related to statistics as they are used in economics (calculations of the Consumer Price Index) and in risk assessment (proportions, risk, relative risk, etc.). She is enthusiastic about learning the material. Future sessions will emphasize verbal explanation of the math so that the formulas and calculations make intuitive sense."
"We finished covering material from Exam 2 including two proportion and two mean tests. We went over how to distinguish if confidence intervals or hypothesis testing should be used when approaching a problem. By the end of the session, we had started going over new material that the student was learning in class. She did a great job of picking the material up and we will be continuing with chi-squared testing as well as ANOVA next week. The student had a fantastic attitude towards the material and has been putting in a lot of time outside of tutoring sessions to practice."
"We worked on the student's h/w on the material on normal distribution, exponential distribution, and uniformly distributed variables. Reviewing this material the week before allowed her to be prepared for answering the questions in the first half of the class. The material on normal distribution requires more practice but she is gaining a mastery of the material. This is essential for the next chapter, which delves more in depth into this variable."
"Student and I discussed two major topics: the normal distribution and the binomial distribution. With the normal distribution, we solved problems related to finding the appropriate "area under the curve" as well as finding critical values given the area, mean, and standard deviation. With the binomial distribution, we discussed and established definitions for probability, p, as well as trials, n. We discussed how to write down all the possible outcomes, and how to find the probability of a single outcome occurring."
"We completed the fourth assignment and started on the section covering t-distributions. We will be continuing this section during the next session. As always, the student's attitude was positive and he did a good job with the material. He got a 93% on this assignment."
"The student and I worked on problems from chapter 7 and 8 of his book to prepare for an upcoming test. The biggest success from the session was clarifying when to use t tests versus z tests and the differences between type 1 and type 2 error and how to calculate those respective values."
"We covered the second half of module 8 on the student's previous homework. We talked about what a test statistic means and how to relate it when referring to z scores. The student was challenged understanding the meaning of a p-value, so we broke it down and I feel that the student has a greater understanding than prior to our session."
