the last one because 7*3=21 14*3=42 and 21*3=63
Hello!
To calculate mean absolute deviation, you find the mean, find the distance between each data point and the mean, add up those distances, and divide by the number of data points.
In this scenario, after Natalia finds the distances, she must add them all up and then divide by the number of data points.
I hope this helps!
I’m doing algebra too and I’m stuck!!!
D. 2.0 I think it's the correct answer...
