To find the mean (average) of a set of data, you need to calculate the sum of all the numbers in the data set and divide it by the total number of values.
Sum = 89 + 80 + 83 + 89 + 91 + 87 + 84 = 603
Total number of values = 7
Mean = Sum / Total number of values = 603 / 7 = 86.1
Therefore, the mean of the set of data is 86.1 degrees.
