Recent Tutoring Session Reviews
"Today we did a little review of correlation and then did some problems where we predicted a y value given a line of regression and an x value. The student isn't having any problems with this material and is already able to complete all the homework problems without trouble."
"We continued to review confidence intervals while emphasizing a new topic: standardized z-scores, their calculation, and their interpretation. She had a little trouble distinguishing between a population distribution and a sampling distribution, but we grounded the concepts in real-life examples such as heights of girls at her school that helped her grasp the conceptual differences. We worked from her previous homework and from her extra credit quiz on z-scores. We will meet again tomorrow."
"The student and I did more work on hypothesis testing, working with proportions using the Z, and means using the T distribution. We found critical values, p-values, and made decisions on rejection of claims."
"Today we covered hypotheses testing on two sample means. The student was challenged, but very attentive and puts much effort in learning what is being presented. She indicated that she is not aware of what is important to know for her exams and so she is a bit anxious. I suggested to her that in situations like this she can see her instructor and ask about this, or she can make up her own questions that she would like answered on the topic she is studying, helping her to sift through the information more easily."
"Basic concepts about normality, z-score stuff and went through some practice problems. Student was having a hard time understanding concepts at the beginning but made it at the end. Practice went pretty well."
"The student and I mostly discussed statistics terms and their uses. We went over ANOVA tests, double histograms, and the differences between discrete and continuous distributions. We also touched on the relationship between variances and standard deviations."
"The student reports that he received an 80 on his last stats test. He hasn't gotten the test back so he doesn't know exactly what he did wrong. He's hoping to do well on his partner-exams that are coming up this week. These exams are cumulative, but he can work with a partner. He and I reviewed using his past exams. He has a good grasp on them again and was able to do the questions correctly on the review. Hopefully he will do well on them. He also told me that he currently has 24 checks of his required 32 for physics. He will try to do as many quests as possible before the term ends. We're hoping to get as many points as possible doing well on his final."
"The student was pleased with her last exam score; she received a B. Today in our session, we covered problems from her homework assignment. Those questions came from chapters 4 and 6. Some of the concepts that we covered were confidence intervals, margin of error, and sample mean. The homework questions were not as complex, and we were able to cover all of the questions during our session."
"Today's was the student's second session and I have to say that I am impressed with her work ethic. She reviewed the material from our first session extensively and has already developed a good understanding of integrals. We then focused on the second part of her homework which involves joint probability distributor mean and variance. So far we've worked on identifying the correct intervals and the student has done a good job doing that."
"Student and I finished reviewing the "random variables" section, and we will be going onto the assignments for conditional probability, among other topics. Student is doing well with the course concepts and is making great progress in the class."
"At the start of the session, the student and I went over the score from his worksheets and exams. The grades show that he has been steadily improving as the semester has progressed. We then went over a worksheet in preparation for the next exam. The topic was on probabilities, including the associated rules as well as conditional probabilities and permutations. He was more confident of the material by the end of the session."
"The student and I completed various homework assignments together during this session. Since it is the beginning of the semester for his statistics course, the topics we covered were: relative frequency, reading graphs, mean, median, mode calculations, and the patterns between skewed and symmetric graphs. He was overall very fluent with the material and understood the concepts. He completed the homework confidently, and when he did make few mistakes it was from calculation errors. While completing the homework, we would discuss the answers. If he got a question wrong, we would review the concept. This was a great strategy because by the end of the session he was much more familiar with the material."
