Summarize two-category data with two-way tables and interpret joint, marginal, and conditional relative frequencies.
Compute a marginal relative frequency
Problem
A row or column total is \(18\) out of a grand total of \(30\). Find the marginal relative frequency.
Big Picture
What this problem is really about
A marginal frequency combines across the other variable, so its numerator comes from a row or column total rather than one interior cell. Because the question asks for that margin’s share of everyone represented, compare the marginal total with the grand total.
