What does the mean represent in a data set?

• A measure of variability

• A measure of center

• The highest value

• The lowest value

How is the mean calculated?

• By finding the middle value

• By adding the highest and lowest values

What does the Mean Absolute Deviation (MAD) indicate about a data set?

• Its highest value

• Its lowest value

• Its variability

• Its measure of center

Why do we take the absolute value of deviations when calculating MAD?

• To increase the MAD value

• To ensure all deviations are positive

• To make the calculation easier

• To find the mean faster
