Essentially:
- If (Mean ‐ Median) = 0, the distribution is symmetrical
- If (Mean ‐ Median) > 0, the distribution is skewed to the right (positively skewed)
- If (Mean ‐ Median) < 0, the distribution is skewed to the left (negatively skewed)
The following image illustrates what each distribution typically looks like:
