Subject: How do I tell SPSS that numbers represent frequencies of
categories and not of individual cases when performing chi-square
test of independence?
I have data in form of frequencies representing categories of two variables. Instead of typing individual cases I would like to only enter frequencies of each category, and request chi-square test of independence. Details of variables and frequencies of each category follows. Variable name equals awareness. highly aware 102, moderately aware 36, no awareness 12. variable name = conservation behavior. high conservation 90, moderate conservation 39, no conservation 21. I would like to type these frequencies in spss and tell it that these are frequencies of categories, and not individual cases.
I tried to weigh cases by frequencies. But I was only able to define one variable as frequency variable. The value I got after requesting chi-square test was 306.4. According to calculation done by hand the answer is not correct. I tried to find the answer of my problem on the web. But most of the tutorials have used pictures to explain data entry. Since I am blind, I was not able to solve my problem from those tutorials.
Any help is most appreciated,
