Question

the dotplot above shows the distribution of calf measurements for 507 adults who attend a local gym. the data is divided into equal - sized subgroups with 25% of the adults in each subgroup. which measure of center can you most accurately estimate from this information?
○ mean
○ median

Explanation:

The data is divided into four equal - sized subgroups (each 25%), which is related to quartiles. The median is the value that separates the lower 50% and upper 50% of the data. Since we know the quartile divisions (25% subgroups), we can use this to find the median. The mean requires knowing the exact values and their sum, which we can't accurately estimate from just the subgroup divisions shown in the dot - plot.

Answer:

median
