Recent Tutoring Session Reviews
"Today we did some final practice with creating confidence intervals and testing claims using sample means and the central limit theorem. Then we covered normal percentile plots and finding a sample size given a desired confidence level and margin of error."
"The student and I resumed where we stopped last time, working on continuous probability distributions and worked all the way through the material being covered on his upcoming test. He had some initial concerns about the normal distribution and sample distributions, but we looked at extra practice problems from those sections, and I think he'll be very prepared for the test."
"The student and I spent this session covering confidence intervals again, but this time using the t-distribution rather than the standard normal (z) distribution. This gave us the opportunity to discuss degrees of freedom and the differences between the t-distribution and the z-distribution. The course instructor seems to prefer students to do the calculations using a special calculator with statistical functions rather than by hand, but we spent time doing it both ways because I want the student to understand what the calculator is actually doing. She is doing very well as handling the computations in this manner. Soon we will be moving into hypothesis testing and we plan to meet again on Monday evening."
"We worked on chapter 4 in the student's book, which included probability theory and calculating probabilities. He seemed comfortable with the material."
"The student and I worked through her problem sheet on binomial statistics. There were several of the questions that she had initially answered one way that we found had different answers. We worked through the details of the solutions, and she understood these solutions and their methods including looking up values in the Normal Table. We also started working on the next Excel assignment and completed the binomial portion of the work. We started the first few exercises of the standard normal portion but ran out of time before the library was closing."
"We covered the student's homework assignment for chapter 8 (binomial distribution and probabilities). We covered mean, std dev, and single and cumulative probabilities. We spent the whole time on completing the homework assignment and not enough time on conceptual understanding. I will send her a summary sheet of the things we covered, how to use the TI graphing calculator for pdf and cdf calculations, calculation of mean and std dev, and examples of solved problems."
"We worked on various concepts with hypothesis testing, and are now solidly in the T-test section. Student is definitely improving greatly in his understanding of the tests. Also worked with Excel and showed him how to get some basic information on data sets from Excel formulas."
"We went over different types of distribution, z-tests, t-tests, binomial tests, probability. We are currently setting up her Statistics and Psychology tests for me to proctor in the upcoming weeks. She has practice problems to look over. She has a great attitude towards the material."
"We went over probability problems that covered sensitivity, specificity, geometric distribution, and the hypergeometric distribution. The student seemed to understand how to do the problems after showing him how to do them. No strategies or study skills were included in this session. I have gained no concerns from this session, although I have gained the victories of helping him with a portion of his set of problems related to probability."
"We reviewed the basics of probability distributions. We went over the definition of distributions and the basics of Poisson and binomial distributions. I recommended that he read the chapters in the book before the material is covered in class to help him understand new concepts."
"This was our first meeting. We covered the overall structure of the course, as well as some background material. His test is on Monday and we will be working on several problem sets. He understands the material and simply needs more practice."
"Today we covered probability again. She's been working on combinations, permutations, independent events, conditional events, unions, and intersections. We went through a new set of problems she received from her professor today. The student was struggling with the application of some of the tricky concepts. The student had a positive attitude towards the material and was eager to learn. In terms of strategies or study skills, I let the student know that when dealing with an "at least once" problem, you solve for the conditional first, then subtract from one. I left the student with the last word problem from the problem set she received today. Wins during the session. The student once again made progress when it comes to understanding what is going on beyond the mere grunt work of it all."
