Applications such as lan-guage modelling for speech recognition and EM Summarize categorical data for two categories in two way frequency tables. endobj Let Xi denote the number of times that outcome Oi occurs in the n repetitions of the experiment. To help with calculations, rounding is an effective way to disclose the relative frequencies. Marginal probability is the probability of an event irrespective of the outcome of another variable. To find a joint relative frequency, divide a data cell from the innermost sections of the two-way table (non-total) by the total frequency. $$(a)\;Joint\;Relative\;Frequency=\frac{Women\;and\;English}{Total\;Frequency} = \frac{17}{150}\approx 0.1133 \\ (b)\;Joint\;Relative\;Frequency=\frac{Men\;and\;Science}{Total\;Frequency} = \frac{3}{150} = 0.02 $$. 323 Poor 272 The joint probabilities occurs in the body of the cross-classification table at the intersection of two events for each categorical variable.
