Name: _____________________________________ Lab #3 Spring08 Page 1 of 5 Lab Partners: ________________________ Lab Day/Time: __________ Part I. Social support & recovery Researchers have found significant relationships between social support and mortality rates in women suffering from breast cancer, such that women with a great deal of social support experience better courses and outcome of their disease, and women in social support groups have a longer lifespan. From Blackboard > Course Documents > Lab Information, Lab #3 open the file Lab3_BreastCancer.sav. The current data consist of information from a longitudinal study of women with early stage breast cancer in which participants were asked about their levels of social support and then time to recovery in months was measured. The data consist of patient ID, age, a rating of their current social support (0-to-10 point Likert scale with 0 being very poor and 10 being strong social support) and time in months until recovery. We are interested in learning about the relationship between levels of social support and recovery time. 1. Looking at the dataset, what is/are the independent variables? There are no IVs. 2. What is/are the dependent variables? What is/are the measurement scales associated with each variable? DV#1: Levels of support on a 0 – 10 Likert Scale with 0 being poor support and 10 being strong social support. Interval Data. DV #2: Recovery Time in months. Ratio Data. Next, we are going to find the measures of central tendency and variability for the sample. ¾ On the toolbar, click on ANALYZE > DESCRIPTIVE STATISTICS > FREQUENCIES. ¾ Move TIME over to the variable(s) box.
