Research Scenario: A social psychologist is studying the differences in the number of Facebook® friends between identical twins raised apart. She believes that twins raised in different environments will have differences in the number of friends, which would help point to the influence of environmental factors over inherited factors on social outcomes. She divides the twins into two groups (“Twin 1” and “Twin 2”), collects the data and creates the table below.

Using this table, enter the data into a new SPSS data file and run a paired-samples t test to test the claim that the identical twins raised apart will have a different number of Facebook® friends. Follow the directions below the table to complete the homework.

Research Scenario: A clinical psychologist is studying whether aerobic exercise improves anxiety in veterans diagnosed with PTSD. Participants agreed to take an anxiety measure before and after a 4 week aerobic exercise plan (5 workouts per week for four weeks). The values provided in the table are anxiety scores (scale measurement) collected before and after the aerobic exercise sessions, with higher numbers indicating higher anxiety. Using this table, enter the data into a new SPSS data file and run a...

Research Scenario A A psychologist is interested in the relationship between color of food and appetite. To explore this relationship, the researcher bakes small cookies with icing of one of three different colors (green, red, or blue). The researcher offers cookies to subjects while they are performing a boring task. Each subject is run individually under the same conditions, except for the color of the icing on the cookies that are available. Six subjects are randomly assigned to each color....

Problem Set 2: Linear Regression Analysis Research Scenario: A social psychologist is interested in whether the number of days spent in a refugee camp predicts trauma levels in recently resettled refugees. He interviews 17 refugees to determine how many days they spent in a refugee camp before being resettled, then administers the Harvard Trauma Questionnaire Part IV (HTQ Part 4), where a higher score indicates higher levels of trauma (Mollica et al., 1992). He compiles the information in the table...

A social psychologist claims to know how many casual friends are in the typical person's social network.  The psychologist states that the average number of casual friends is 11.  You question the validity of this researcher's claim and decide to conduct your own study.  You interview a random sample of people and determine for each the number of friends or social acquaintances they see or talk to at least once a year.  Your data are below: 16 4 6 11 16 4 8 7...

5.34 Number of friends on Facebook. To commemorate Facebook’s 10-year milestone, Pew Research reported several facts about Facebook obtained from its Internet Project survey. One was that the average adult user of Facebook has 338 friends. This population distribution takes only integer values, so it is certainly not Normal. It is also highly skewed to the right, with a reported median of 200 friends. 8 Suppose that σ = 380 and you take an SRS of 80 adult Facebook users....
