• Median

• Mean

Which statistic measures the spread of data?

• Median

• Mean

• Mode

The range of a data set is calculated by:

• Adding the largest and smallest values

• Subtracting the smallest value from the largest value

• Dividing the largest value by the smallest value

• Finding the difference between the mean and median
