Final answer:
In Mathematics, specifically statistics, a two-way table includes joint, marginal, and conditional frequencies. Row relative frequencies are calculated by dividing the row's frequencies by its total, while cumulative relative frequencies add up as you go down the rows.
Step-by-step explanation:
The subject of the question is Mathematics, specifically focusing on the topic of frequencies within two-way tables. When dealing with two-way tables, row relative frequencies are calculated by dividing the frequency of each category by the total frequency in the row. Marginal distributions reference overall totals for one variable without consideration of the other variable, while conditional distributions focus on frequencies for one variable while holding another variable constant.
To calculate a row relative frequency, sum the joint frequencies in a row to get the total for that row, and then divide each joint frequency by this row total. The cumulative relative frequency is found by adding the relative frequency of the current row to the cumulative total of the previous rows. This process is crucial in understanding two-way tables, as it allows for the consideration of how two categorical variables may relate to one another.
