I am creating Results for Research project using SPSS. I have a sample size of 80. 40 males, 40 females. I have three variables; gender, age, and exercise time. Should I be using a parametric test or non parametric test? What other non parametric or parametric tests do I need to use?

Pearson Correlation between age and exercise time are shown in Table 5. Table 5. Pearson Test Exercise Time Age (yrs) (Minutes) Age (yrs) Pearson Correlation 1 673 Sig. (2-tailed) 000 N 80 80 Exercise Time (Minutes) Pearson Correlation 673" Sig. (2-tailed) 000 N 80 80 ** Correlation is significant at the 0.01 level (2-tailed). Spearman Correlation between age and exercise time are shown in Table 6. Table 6. Spearman Test Exercise Time Age (yrs) (Minutes) Spearman's rho Age (yrs) Correlation Coefficient 1.000 743" Sig.
