I'm in the number crunching phase of some research. I had an advanced stats class two years ago, hence, the haziness on the interpretation end. I compiled the data from the Metropolitan Chicago Information Center (MCIC) and developed two hypotheses relative to data about residents' perception of crime in their neighborhoods for the years 1992 and 1996. Here are the hypotheses:
Hypothesis 1 - If experience is the prime determinant of perception, males and females have similar experiences of crime in their neighborhood.
Hypothesis 2 - If media exposure shapes perception, people with different education levels have different exposure to the media and should have different perceptions of crime in their neighborhood.
The following questions need to be resolved:
1) What is the difference in perception between males and females in 1992? It appears that females feel less secure or, as the lit review indicates, they tend to feel more vulnerable to crime and perceive slightly more crime than males. Test for significance. Is this difference significant?
2) Repeat the process for 1996. What is the difference between males and females in 1996? Test for significance. Is the difference significant?
3) What are the changes in male perception between 1992 and 1996 and compare to changes in female perception. It appears that there is virtually no difference. Test for significance. If there is no significant difference then it appears that this finding supports Hypothesis 1.
4) What are the differences in perception between groups of differently educated persons in 1992? It appears that highly educated persons perceive less crime. Test the difference for significance. Is it significant? If it is, then this finding suggests that media does not shape perception.
5) Repeat the process for 1996. Test for significance. Is it significant?
6) What are the changes in perceptions between 1992 and 1996? It appears that highly educated persons perceived a smaller drop in crime. Test for significance. Is it significant? If it is, then the finding suggests that media does not shape perception and Hypothesis 2 is rejected.
At this point it would be great to view the results in terms of a minimum of chi and t-tests with accompanying info for SD, etc. I have been trying to slog my way through SPSS and another pair of eyes and sharper interpretation skills would be a huge benefit.
Also, could you provide me your email (contact information) so that I can clarify things further if need be.
<br>According to my experience in using SPSS, you first have to construct a linear model that includes a dependent variable and independent variables. Then another point is that you have to know what kind of analysis you want to run through SPSS program. Do you have the data available for a particular year for the independent and dependent variables that will lead ...
