Exercise 8.4 A political scientist wants to find out if there is a correlation between listening to a newscast and an individual’s mood. This researcher recruits a group of participants and has them listen to a newscast that was recorded earlier that morning. Participants are instructed to listen for as long as they want; when they are done listening, the researcher writes down the listening duration and then asks each participant to complete the Acme Mood Report (AMR), a self-administered instrument that renders a score between 0 and 100 (0 = very bad mood, 100 = very good mood).

Data set: Ch 08 - Exercise 04A.sav Codebook Variable: minnews Definition: Number of minutes of news listened to Type: Continuous Variable: amr Definition: Acme Mood Report score Type: Continuous (0 = very bad mood, 100 = very good mood)
