WebMay 10, 2024 · Real observations rarely have a Pearson’s median skewness of exactly 0. If your data has a value close to 0, you can consider it to have zero skew. There’s no standard convention for what counts as “close enough” to 0 (although this research suggests that 0.4 and −0.4 are reasonable cutoffs for large samples).

Web6.2.2 Bowley's Measure of Skewness This measure is based on quartiles. For a symmetrical distribution, it is seen that Q, and Q3 are equidistant ftom median. Thus (Q3 - Md) - (M, - Q,) can be taken as an absolute measure of skewness.
