In a negatively skewed distribution, the correct inequality is:

  • A.Mean < median < mode
  • B.Mode < median < mean
  • C.Mean = median = mode
  • D.Mean < mode < median

Answer: A

In a negatively (left) skewed distribution, the tail is on the left side. The extreme low values pull the mean to the left.

The order of the central tendencies is: Mean < Median < Mode.

Conversely, in a positively skewed distribution, the order is Mode < Median < Mean.
