• Find the Mean of the data

• Find the Absolute Values of the data

• Find the Mean of the Absolute Value set

• Subtract each data value from the Mean.

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

• Find the mean of the data

• Find the Mean of the Absolute Value set

• Subtract each data value from the mean

• Find the Absolute Values
