Some statistics tell us how many members of one class (S) belong to each of a number of other classes (such as P, Q, and R) .These statistics are called:

A) spreadsheets
B) distributions
C) scatter totals
D) pigeonhole tallies
E) arrays

The statistics described in the question are called distributions, which show how data is spread or distributed across different categories or classes. The other choices, such as spreadsheets, scatter totals, pigeonhole tallies, and arrays, are not directly related to this concept.
