Statistics- how can i know if my data is suitable to be analysed using parametric tests on SPSS?

i've read lots of definitions of parametric tests and the requirements of them, but i'm still unsure if my data has "homogeniety of varience" or "normal distribution"- can anyone tell me in very simple terms how i can find out if it is suitable or not? i'm using a questionnaire so want to see if there are correlations between answers of different questions

Why don't you use statistical software like prism or SPSS and use kappa test
