    Mason mistakenly calculated the conditional relative frequency for female students who prefer playing sports to be 21%. What statistic did Mason actually calculate, and what should he have done differently? He calculated the marginal relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 34%. He calculated the joint relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 50%. He calculated the marginal relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 50%. He calculated the joint relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 34%.

    Joint relative frequency is the ratio of the frequency in a particular category and the total number of data values. This would be the 18 out of 87 which is 21%. Conditional relative frequency numbers are the ratio of a joint relative frequency and related marginal relative frequency. This would be 18 out of 53 which is 34%

    What he did was number of females who liked playing sports divided by the total number of people instead of the total number of girls
