87+87+81+86+89+83+89= 602. Divided by 7 because that’s how many numbers there were is 86 and that is your mean/average.
The mean change in the forecasted high temperatures is of 4.33 degrees.
------------------
- The mean of a data-set is given by the sum of it's observations, divided by the number of observations.
- There are 7 days, thus, there will be 6 changes.
------------------
- From Tuesday to Wednesday, the change is of |87 - 87| = 0.
- Following this logic, the changes are of 6, 5, 3, 6, 6.
- Thus, the average change will be of:
[tex]A = \frac{0 + 6 + 5 + 3 + 6 + 6}{6} = \frac{26}{6} = 4.33[/tex]
The average change in the forecasted high temperatures is of 4.33 degrees.
