Award-Winning Statistics Tutors serving Reading

We went over the student's independent project and how to analyze the different tests. The tests included summary statistics, bar graphs, histograms, chi-squares, scatterplots, and regressions/correlations. She did very well with the different tests, so I just helped her organize her data and answer the professor's questions.

The student only had one homework question and it wasn't too difficult. We spent some time on the computation and then on some of the easier problems.

Yesterday, the student and I covered 9.3 and 9.4. We discussed each concept and then used a calculator to solve. The approach is encouraged by the teacher, and allows him not to become anxious about memorizing the formulas.

Today, we studied for the student's midterm next Tuesday. We worked a lot on z scores and finding the area under a normal curve using the 68/95/99.7 rule. She feels confident that she will do well on her test. I look forward to hearing about it!

Today, we worked through problem sets covering normal distributions, sampling distributions, and confidence intervals. We talked about the different types of data (qualitative and quantitative along with discrete and continuous), types of sampling procedures (simple, stratified, cluster, and systematic), the empirical rule, calculating standard error, and how to calculate and interpret confidence intervals. This material the student understood much better. I think since this course is online, the student struggles a bit with connecting the terms and how to use them to answer the homework problems. But my help verbally explaining the topics and explaining them in differing ways is really helping his comprehension.

We reviewed fundamental concepts in probability, the use of Venn diagrams, the addition rule, and the multiplication rule. The student worked through some practice problems, and she was able to apply what we discussed. Moreover, we reviewed tree diagrams and discussed conditional probabilities. I asked her to practice on her own using the end of chapter review exercises.
