1. Using statistical significance (p value), report whether you conclude that Q16 is normally distributed in the population.
- Using the same World Cup data you have used for take-home exams and edited/manipulated (edre7200fall2016sample1dataWC.xlsx), create and submit the output like used in the test booklet below. Include all options and additions I have provided (e.g., the data labels in the scatterplot and residuals in the chi-square). Ideally you will replace my figures/images with your own output right in this test booklet. You may work on the SPSS portion of the exam with others, all other answers must be completed independently.
- The analyses you need to run are in the yellow section above the SPSS output in each section. If you run them wrong you will lose points for having the wrong answers to items based on those analyses (so run them correctly). For example, you’ll want to be certain that Q16, Q19, Q21, and Q22 missing value codes are correct and that you recoded Q09A correctly. Be sure you have added your initials to variable names and variable labels so I see your initials in the output.
- In order to earn ANY remediation credit, you must answer ALL items in EVERY section where you lost ANY points, except the one-sample t test section. For example, if you lost any points on item #1 before, you must complete items #1-#3 below (the items in Section 1). In the one-sample t test section (Section 2), you must answer all items on any page where you lost any points (as paginated in the original test booklet below — not new pages that occur as you enter answers — so the first page is items #4-7, the second page is items #8-13, and the third page is items #14-18).
- I will average your scores item-by-item. Items fully correct here are worth 3 points. If you earn full credit, those 3 points will be averaged with the points you received on the first exam to obtain your new score (e.g., if you scored a 0 on #1 before and earn 3 here, your new item score will be 1.5; if you scored 1 before and a 3 now, your new score is 2, etc.). Of course, if you got full credit before and you get full credit now, you will get 3 points (but if you do not receive full credit here, then your item score will be averaged — so be sure to get full credit here). For any items you did not need to answer in the remediation test booklet below, you will keep the 3 points from the original Exam 2.
- Anyone who scored lower than 90% (or under 150 points) on Exam 2 (as recorded on Blackboard) and wants to earn any credit for the remediation must respond to Section 7.
For items in the section before the next divider like this, use the following data and information.
|1. Using statistical significance (p value), report whether you conclude that Q16 is normally distributed in the population.
2. Using a confidence interval for skewness, report whether you conclude that Q16 is symmetric in the population (and if not, why not).
3. Using a z statistic for kurtosis, report whether you conclude that Q16 is mesokurtic in the population (and if not, why not).
