Distribution Types

What types of data distributions exist? Check all that apply.

• Symmetrical

• Skewed

• Bimodal

• Unimodal

• Average

In a symmetric distribution (bell-shaped), the..

• mean = mode

• data is skewed

• mean = median

• all data points have the same value

Symmetrical (bell-shaped) distribution has a...

• vertical line of symmetry

• skewed data to the right

• skewed data to the left

• all data has the same value

In a skewed distribution...

• data can only skew to the right

• mean = median

• Data points do not follow any pattern

• one side of the distribution has more values farther from the bulk of the data than the other side.

Given this data distribution...(check all that apply)

• mean = median

• mean is greater than the median

• this data is negatively skewed

• this data is positively skewed

Bimodal distributions...

• has two very common data values (peaks) seen in a dot plot or histogram

• are always symmetric

• mean = median

• may be skewed to the right of to the left

This data is...

• Positively skewed

• Negatively skewed

• symmetrical

• bimodal

This data is...

• skewed to the right

• bimodal

• symmetrical

• uniform
