Examining the task, we are asked to pair each item on the left with the appropriate expression on the right, noting that not every right-hand item may be used. The four left-hand prompts correspond to standard probability/statistics concepts, and we should map them to the most fitting right-hand option. First left item: 'This summarizes the relationship between two variables.' This description points to a tool that displays how two variables relate, typically in a table that shows joint frequencies or probabilities for combinations of outcomes. The most suitable match among the options is 'Contingency Table,' which is exactly a cross-tabulation used for two variables. The ......Login to view full explanation
