BlackTom AI · Accepted Answer

The question asks: Which of the following gives the proportion of items in each bin?
Option A: 'Bin proportion' — This term suggests a notion of proportion but is not the standard terminology used to describe the share of items per bin in a distribution. It’s vague and not the common label for proportions within bins, so this is not the best choice.
Option B: 'Class size' — In a frequency distribution, class size typically refers to the number of observations falling into a bin or class, i.e., the count, not the proportion. It measures quantity, not the relative share, so this option does not describe proportion.
Option C: 'Relative frequency' — This is the standard term for the proportion of items in each bin. Relative frequency is computed as the bin count divided by the total number of observations, yielding a proportion or percentage for each bin. This aligns exactly with the definition of proportion across bins.
Option D: 'Frequency' — Frequency usually denotes the raw count of items in a bin, not the proportion. It tells you how many observations fall into the bin, but not the share of the total that bin represents.
In summary, Option C correctly identifies relative frequency as the proportion corresponding to each bin, while the other options either refer to counts, general or ambiguous terms, or do not express proportion.
