Skewed Left or Right

• When a distribution is skewed left the mean is less than the median

• When a distribution is skewed right the mean will be more than the median.

Uniform Distribution

• In a uniform distribution, the data values are spread out equally among the intervals.

• The values are the same or close to the same.

• The data is distributed evenly around the mean and the mean and the median are close to the same.

Bell or Symmetrical Distributions

• Symmetrical distributions of data can also be called normal or bell shaped.

• Since their distribution is fairly normal, the mean and the median will be close to the same.
