To calculate the mean absolute deviation, first calculate the mean of the number of pizzas served:
Mean = (29 + 58 + 15) / 3 = 34
Then, calculate the absolute deviation for each data point by subtracting the mean from each data point:
|29 - 34| = 5
|58 - 34| = 24
|15 - 34| = 19
Calculate the sum of the absolute deviations:
5 + 24 + 19 = 48
Finally, divide the sum of the absolute deviations by the number of data points:
48 / 3 = 16
Therefore, the mean absolute deviation is 16.
Using the mean from #9 Calculate the Mean Absolute Deviation. Sherry has an after school job at Pap John's. Her boss keeps track of how many pizza she sells each day. During her last 5 days of work, she served 29, 58,15 pizzas.
