Which statistic measures how many observations fall into a category?

This question tests understanding of what statistic describes the number of observations in a category. The count directly tells you how many data points fall into that category. Summing values changes magnitudes rather than tallying how many items belong to a category. An integral deviation isn’t a standard measure for counting items in categories and serves as a distractor. A frequency distribution shows the counts for all categories, but it’s a representation of counts rather than the single statistic that reports the exact number in one category. So the statistic that measures how many observations fall into a category is the count.
