1st Review: MAD and Scatterplots

What is Mean Absolute Deviation?

• The mean of the data

• The absolute value of the mean

• The variation of data values around the mode

• The average distance between the data values and the mean

What is the first step when calculating the Mean Absolute Deviation?

• Find the distance each value is from the mean
• Find the mean of the distances
• Find the mean of the data

What is the second step when calculating the Mean Absolute Deviation?

• Find the distance each value is from the mean
• Find the mean of the distances
• Find the mean of the data

What is the third step when calculating the Mean Absolute Deviation?

• Find the distance each value is from the mean
• Find the mean of the distances
• Find the mean of the data

What is another word for average?

• Mean
• Median
• Mode
• Range
