Shape and Spread Distributions

11.5 Center, shape, & spread of data

Comparing Functions

• Middle = Median; which function has a larger median?

• Larger range = larger standard deviation

• Which function has the greatest standard deviation?

Shape of data: Normal

• Most of the data is in the center of the graph

Shape of the data: Skewed Left

• There is very little data on the left side of the graph

Shape of the data: Skewed Right

• There is very little data on the right side of the graph

Multiple Choice

Which statement is true about the graphs?

• Function B has a smaller standard deviation because it has a smaller range
