I think that so...............
Answer:
And we can calculate the deviations from each value like this:
And the mean absolute deviation would be:
Step-by-step explanation:
For this case we have the following dataset given:
101.5 98.7 95.4 92.3 109.8 104.7
We can calculate the mean with the following formula:
And replacing we got:
And we can calculate the deviations from each value like this:
And the mean absolute deviation would be:
