He has assigned randomly 15 children to either a control group or an experimental group. Children in each group were given a wellrespected norm-referenced test of reading achievement at pretest and at West. This test has a mean of 100 and a standard deviation of 15. Students in the control group received the regular reading program; other students in the experimental group received the m Reading Program. Having heard of your growing expertise in statistical analysis, Dr. Schmedlap has come to you with his data and asked you to determine whether his reading program results in greater achievement than the regular reading program. Professor mm would also like a full explanation of what you have done with his data and why you have to choose a particular analytic technique. As is typical in statistical analysis, there is a number of ways to answer Schmedlap' 5 question. Please do not compute every possible analysis that might be done on these data. Choose an appropriate approach and tell the story that arises from the analysis, with any needed cautions. Make sure to explain and tojustify what you have done. Questions 1. plan, execute and justify a set of analyses in order to answer a research question 2. examine the assumptions required for the set of analyses you have chosen and conduct other preliminary analyses, such as compute means and graphs 3. reach a set of conclusions following from your analyses and provide any needed cautions concerning your conclusions
