Exercise 7.9 In an effort to discover ways to boost morale, an investigator wants to assess the effects chocolate has on attitude. The researcher recruits a group of participants and has them complete the Acme Attitude Survey (AAS), which renders a score ranging from 0 to 100 (0 = very bad attitude, 100 = very good attitude). After gathering the (pre)tests, the researcher serves each participant a generous slice of chocolate fudge cake. One hour later, the researcher

administers the AAS a second time. Data set: Ch 07 - Exercise 09A.sav Codebook Variable:
