The sample size for male groups is significantly higher (N = 235) in comparison to female group (N = 30). Repeat descriptive statistics on this data. The value obtained will be assessed using a set decision rule to determine the likelihood that the difference in the correlation noted between the two groups could have been due to chance. It is important to note that this process is different from testing the statistical significance of the correlation coefficients reported in the output table above.
