Recent Tutoring Session Reviews
"The student used a math program online and a T1-84 calculator in this session. I was able to teach her concepts such as how to read a t-table and find the critical values, how to decide whether or not to reject a null hypothesis, and how to state the conclusion."
"This session focused on hypothesis/ significance testing for proportions and means. We walked through the five-step process to set up, conduct, and draw a conclusion (a.k.a. statistical inference) from the test. There are two challenging concepts in this lesson where we spent a significant amount of time. First, how to establish your null and alternative hypothesis based on the question asked and second, what are you actually concluding from the results of your test. The student was listening intently and asking questions. I left her with a reference sheet for the five-step process, calling out a few reminders and summary statements."
"This session was spent practicing selecting the appropriate test in the calculator, inputting the data, and analyzing the results to determine whether to reject or fail to reject the null hypothesis. In preparation for the next session, the student will be reviewing the second half of the final exam review documents and we will be using the next session to determine the areas/topics that require the most attention based on the student's comfort level."
"This was my first session with the student, and it went very well. We were able to get through all of her questions during our session, and I believe that she now has a better understanding of what she needs to do to figure out some of the problems. We went over how to approach binomial distribution problems and how to interpret what needs to be filled in in the equation to solve it correctly. We also discussed independent and dependent variables and how to tell the difference between the two of those in a given problem. The last things we discussed were different things about probability and also the basic counting rule. She had a pretty good understanding of these concepts, and I was able to clarify a few things for her. I believe that she will do well on her test tomorrow."
"Today the student and I continued our work on contingency tables, this time adding in the probability notation. We spent quite a bit of time working on Bayes' Theorem. We also went over tree diagrams, and how to use R. The student is doing well, although this material is challenging. It is also difficult to explain in an online environment, but I was able to figure out a way to go over the concepts with her. The two areas where she is struggling most is with differentiating between mutually exclusive and independent, as well as Bayes' theorem. We'll go over these more during our next session."
"Today the student and I covered measures of spread and dispersion as well as reviewed types of graphical summaries, he demonstrated a solid foundation going into his first Statistics exam in a few weeks. We then continued to review Elasticities and Good Types for his upcoming economics exam. The student clearly had prepared."
