Question

which distribution has the smallest median? dot plots for set a, set b, set c options: set a, set b, set c

Explanation:

Step1: Understand Median in Dot Plots

The median of a data set represented by a dot plot is the middle value when the data points are ordered. For a dot plot, we can count the number of dots (data points) and find the middle one (or average of two middle ones for even counts).

Step2: Analyze Set A

Looking at Set A's dot plot, the dots are concentrated on the left - hand side (lower values) with some scattered dots on the right. The majority of the data points are at lower numerical values compared to Sets B and C.

Step3: Analyze Set B

Set B's dot plot has data points concentrated on the right - hand side (higher values) compared to Set A. So the median of Set B will be at a higher value than that of Set A.

Step4: Analyze Set C

Set C's dot plot has data points starting from 86 and going to 94 +, which are all relatively high values. The median of Set C will be at a higher value than that of Set A.

Answer:

A. Set A
