Problem Set 1: Research Scenario: A developmental psychologist is studying the amount of time young people spend daily on social media in her community. She surveys a sample of nineteen 16 to 24 year-olds, who report the number of minutes per day they spend on social media networks. The data are given in the table below. According to the Global Web Index (GWI, 2019), the average daily number of minutes spent on social media sites in the general population of 16-24 year-olds is 181 minutes (https://www.digitalinformationworld.com/2019/01/how-much-time-do-people-spend-social-media-infographic.html). Using the data in the table, set up your data file in SPSS and conduct a one-sample t test to determine whether this sample spends a significantly different number of minutes per day on social media than the general population. Create a histogram to display the distribution of the data.

Problem Set 2: Research Scenario:  The Davidson Trauma Scale (DTS) (Davidson, 1997) is a self-report instrument that indicates the presence and severity of trauma symptoms. It is often used to detect PTSD, with scores ranging from 0 to 136, and a mean in the general population of 11 (Davidson et al., 2002). A clinical psychologist is interested in measuring trauma in a sample of paramedics at the hospital where she works. Using the data in the table below, set up your data file in SPSS and conduct a one-sample t test to determine whether this sample scores higher than general population on the DTS. Create a histogram to display the distribution of the sample’s DTS scores.
