Question

identify the answer choice that best describes the shape of the distribution.
answer attempt 2 out of 3
skewed to the right
skewed to the left
symmetric
uniform

Explanation:

Step1: Analyze the histogram's symmetry

Check if the left and right sides of the peak (around the middle bar) mirror each other. The heights of bars on either side of the central (or near - central) bar seem to balance out. For example, the bar at 0 - 14 and 70 - 84, 14 - 28 and 56 - 70, and the central bar around 28 - 42 have relatively symmetric frequency distributions.

Step2: Eliminate other options

• Skewed to the right: Would have a longer tail on the right (higher values), but here the right - side bars don't form a long tail.
• Skewed to the left: Would have a longer tail on the left (lower values), but the left - side bars don't form a long tail.
• Uniform: All bars would have roughly the same height, which is not the case here as there is a peak in the middle.

Answer:

Symmetric
