I am Lost with SPSS

Postby samlee21 » Tue Mar 13, 2012 1:31 am

Hello,

I need some help in SPSS. I have four variables. These are all
instances of eyewitness misidentifications coming from 85cases of
criminal exonerations. There are certain cases that may have 2 or more
witnesses that identify the individual.

Nonwhite defendant and white victim: 49
White defendant and white victim: 14
Nonwhite defendant and nonwhite victim: 36
White defendant and nonwhite victim: 4

What test can I use to measure the relationship among these four
variables? Am I missing a variable to measure all four of these?

I am trying to prove that it is more likely for ID mishaps to occur
when races between def. and vic. are different. I need your
suggestions. Thank you!

Try recoding your data into 2 columns:
different races (yes/no) misidentification occured (yes/no)

Then create a crosstab and do chi-square test (Analyze - Descriptives - crosstabs in SPSS).
