Question:
25. Baker and Moore (2008) surveyed 58 people when they first started using MySpace (the researchers called this “Time 0”) and again 2 months later (referred to as “Time 1” by the researchers). At both time points, the participants completed a measure of social integration (a sense of belonging to a group of friends). Also, at Time 1, the researchers examined participants’ MySpace profiles to see whether they had started blogging in the past 2 months. The researchers used t tests for dependent means (which they refer to as paired sample t tests) to test whether bloggers and nonbloggers differed in their level of social integration from Time 0 to Time 1. Here is how the researchers reported the results: “Paired samples t tests showed bloggers were significantly higher in social integration at Time 1 than Time 0, t1302 = 3.19, p 6 .01, . . . with no difference for nonbloggers, t 1262 = -0.370, p 7 .05.” Explain these results to someone who is familiar with the t test for a single sample but not with the t test for dependent means.
