CCSS.HSS.ID.A.4

In a uniform distribution...(check all that apply)

CCSS.HSS.MD.A.2

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.

CCSS.HSS.ID.A.3

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

• mean = median

• mean is greater than the median

• this data is skewed to the left

• this data is skewed to the right

CCSS.HSS.ID.A.3

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
