Concept explainers
To check: whether the given histogram is uniform or symmetric, or skewed.

Answer to Problem 15PPE
Symmetric histogram.
Explanation of Solution
Given:
The given data shows points per game.
Concept used:
Symmetric histogram:
If a vertical line can divide the histogram in to two parts that are close to the mirror image, then the histogram is symmetric.
Skewed histogram:
If a histogram has one peaks that is not in the center, then the histogram is skewed. If most of the data are on the right, with a few smaller values showing up on the left side of the histogram, the data are skewed to the left.
Uniform histogram:
A uniform shaped histogram indicates data that is very consistent; the frequency of each class is very similar to that of the others. A data set with a uniform-shaped histogram may be multimodal the having multiple intervals with the maximum frequency.
Calculation:
From the above histogram, it is clear seen that the halves are close to mirror image.
Thus, the histogram is symmetric histogram.
