What is the mean of the data set?
85, 97, 84, 88, 95, 100, 81

The mean of the given data set is 90.

Step-by-step explanation:

Here, the given data set,

85, 97, 84, 88, 95, 100, 81

Since, the number of the observation = 7,

And, the total sum of all observation = 85 + 97 + 84 + 88 + 95 + 100 + 81 = 630

Hence, the mean of the given data set is 90.
