In a symmetric histogram centered at 75, which measure of center is most appropriate?

Explanation:
Symmetry around a central value means the deviations from the center balance out. The mean is the average of all data points, so it sits at that balance point. Since the histogram is centered at 75, the mean is 75, making it the natural measure of center to report. It uses every value and underpins many statistical methods, which is why it’s preferred here. The median would also be 75 in a perfectly symmetric shape, but the mean’s reliance on all data makes it the go-to choice. The range measures spread, not center, so it doesn’t describe the central tendency.
