Sex is a nominal variable which is also called independent variable while doing Anova test.
4 cells (100.0%) have expected frequencies less than 5. The minimum expected cell frequency is 3.0.
The value under "Chi-Square" is .0000 because the cell frequencies were all equal. As usual, statistically significance results are indicated by "Asymp. Sig.[nificance]" values below .05. Obviously, this example is NOT statistically significant. In words, these results indicate that the obtained frequencies do not differ significantly from those that would be expected if all cell frequencies were equal in the population.
The chi-square test for independence is a test of whether two categorical variables are associated with each other
