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).
