Question

thirty - four high school students were surveyed and asked how many siblings they have. the dotplot below displays the distribution of responses. what is the shape of the distribution of the number of siblings? skewed to the left bimodal symmetric skewed to the right unimodal symmetric

Explanation:

Step1: Identify the mode(s)

The data has two peaks (at 2 and 3 siblings), so it is bimodal.

Step2: Check symmetry

The distribution on the left - hand side of the peaks is not a mirror image of the distribution on the right - hand side of the peaks. Also, the tail on the right side (towards higher number of siblings) is longer. This indicates right - skewness.

Answer:

skewed to the right
