WebbChapter 3 Measures of Shape. A measure of shape tells us how symmetrical or asymmetrical a set of data is. Skewness is a measure of shape, and can be negative (skewed to the left, or negatively skewed), 0 (symmetrical), or positive (skewed to the right, or positively skewed). This can be demonstrated via the histograms below: Webb22 mars 2024 · When determining how to calculate skewness and analyzing central tendencies of data distribution, the following are used as measures: Mean: The average of the numbers in a data distribution.
