• By dividing the sum of values by the number of values

• By finding the range of the data set

What is the mean absolute deviation (MAD)?

• The difference between the highest and lowest values

• The sum of the distances of each data point from the mean, divided by the number of data points

How is the median of a data set determined?

• By finding the average of all values

• By identifying the middle number in an ordered set

• By subtracting the smallest value from the largest

• By calculating the sum of all values

What is the term for the difference between the greatest value and the least value in a data set?

• Variability

• Consistent

• Range

How is "variability" defined in a data set?
