Project Part II Grading Criteria

Project Part II

_____ Confidence Intervals (10 points)

bulletCompute a 95% confidence interval for each of your quantitative varibles.
bulletConsider each qualitative variable as a binomial variable (only two possible answers).  For example, if you asked "What year are you?"  then group them into underclassmen or lowerclassmen.  Compute a 95% confidence interval for these binomial variables.
bulletCompute at least 3 two-variable confidence intervals.  For example, if you asked people their year and GPA, you might consider the difference in the average GPA of upperclassmen and lowerclassmen.
bulletYou do not have to type your computations.  You can do them by hand and attach them as an appendix at the end of the report.

_____ Hypothesis Tests (10 points)

bullet Formulate at least 5 good hypotheses and test them.  At least 3 should be two-variable tests.  For example, you might test if the GPA of lowerclassmen is greater than the GPA of upperclassmen.
bulletYou do not have to type your computations.  You can do them by hand and attach them as an appendix at the end of the report.

_____ Analysis of the Results (20 points)

bulletDiscuss the sizes of your confidence intervals. Were any too large to be meaningful? If so, how many measurements (what should n be?) to find an interval small enough to be useful?
bulletDiscuss each of the hypothesis tests you conducted. What did you find?  Was it what you expected? Why do you think that was the case? 
bulletWhat are the real-world implications of your results?  Give any other particularly impressive observations.

_____ Report Format (5 points)

bulletReport looks professional and is well-written.  Spelling and grammar are correct.  It is written as a report, not a list of answers to questions.
bulletThe report is well-organized and readable.  
bulletInclude any of the graphs or calculations you did for Part I that help illustrate your results. (In some ways, the goal of Part I was to get a feel for the data, while Part II tests your impressions and presents your complete results. 
bulletColor and graphics used well.
