Assignment 4

Graduate Research, Assignment 4: Data Description and Interpretation.
For the crosstabulation below, what was the percentage of positive outcomes for those who received the intervention? How many of the total group had "Not Positive" outcomes? Describe whether there is a relationship between receiving the intervention and a successful outcome. Give your reasons for saying there is or is not a relationship. If there is a relationship, discuss the nature of the relationship and how strong it is. Indicate what inferences, if any, you make from the data. If you do not think there is a relationship, describe what evidence would have to be present to conclude there is a relationship and indicate what inferences you would make if the relationship were significant. Discuss any difficulties that you see present in making an inference from the data. The grade will be based on the accuracy of your description, the appropriateness of your inferences, and any special difficulties in the interpretation that you identify. One to two pages.
