Dependent Sample t-Test Activity 1. You want to test a new therapy for globophobia (fear of balloons in general... this is different than phonophobia, which is the fear of the sound produced when popping balloons). You select five people and test their responses to a picture of balloons. Based on heart rate you develop a globophobia score that ranges from O (no fear) to 20 (terror). Following therapy, you get a second measure. NOTE: This is actually too small an n for a real study. Here are your data…..
