Which function would you use to display a value based on a logical condition?

The function that effectively displays a value based on a logical condition is the one that utilizes the "IF" function. This function evaluates a logical test and returns different outputs depending on whether the condition is met.

The structure of the "IF" function is designed specifically for this purpose, allowing users to specify what to display if the condition is true and what to display if it is false. For instance, if you have a condition where you want to check if a student's score is above a certain threshold, the IF function can return "Pass" if true and "Fail" if false. This versatility in handling logical conditions and providing distinct outputs makes it the ideal choice for the given question.

In contrast, the other functions listed serve different purposes: one aggregates data based on a condition, one looks up values in a table, and another counts instances that meet a specific condition. However, they do not return different outputs contingent upon a logical statement like the IF function does. Thus, utilizing the IF function is the most appropriate choice for displaying values based on logical conditions.
