Measures of Center & Spread

Multiple Select

Select the (2) measures of CENTER.

• Mean

• Median

• IQR

• Range

Multiple Select

Select the (2) measures of VARIABILITY.

• Mean

• Median

• IQR

• Range

​

​

​Remember!

Mean and Range ARE affected by outliers and therefore are not great choices when outliers are present.

​Median and IQR ARE NOT affected by outliers as much and therefore are a better choice when outliers are present.
