ANSWER IN BULLET POINT FORMAT
Q1. Using the 1978 data from the RAND Corporation, produce scattergrams for the following pairs of variables:
Age on first arrest (age1arre) by age on first conviction (age1conv)
Number of robberies (rob#) by number of burglaries (burg#)
Number of profit-oriented crimes (profcri#) by number of drug transactions (drug#)
Provide a short interpretation of the scattergrams using the discussion forum link above. Do they suggest a weak, moderate, or strong correlation?
Q2. Using the 1978 data from the RAND Corporation, you want to investigate whether there is a significant correlation between criminal and legitimate income.
First, log the two variables to normalize them.
Run a correlation for these two variables.
Report and interpret your results.
Q3. You want to get an overview of the relationship between several interval variables. Using the Criminal Careers, Criminal Violence, and Substance Abuse in California (1963-1983), compute a correlation matrix for the following variables:
Dominance (tdo)
Self-acceptance (tsa)
Self-control (tsc)
Empathy (tem)
Depression (mmpid)
Paranoia (mmpipa)
– Write a brief description of selected findings (i.e., strongest and weakest correlations). Report and interpret results.
– Pay particular attention to depression: what are the main correlates of depression? Offer explanations for these results.
– How much variance does depression have in common with paranoia? With self-acceptance?
