WebThe histogram below shows a typical symmetric distribution. For symmetric distributions, the mean is approximately equal to the median. The tails of the distribution are the parts to the left and to the right, away from the mean. The tail is the part where the counts in the histogram become smaller. Webhistogram for quantitative data. A shape may be described by its symmetry, skewness, and/or modality. PART B: SYMMETRIC DISTRIBUTIONS Example 1 (Symmetric, Bell-Shaped Distribution) The bell curve below is perfectly symmetric, because it can be divided into two halves (a left half and a right half) that are mirror images of each other.
