Question

Find the mean, median, and mode of each set of values.

1.) Customers per day: 98 87 79 82 101 99 97 97 102 91 93​

Answer 1

Mean = 93.3 ( to nearest tenth).

Median = 97.

Mode = 97.

Explanation:

Arrange the data in ascending order:

79 82 87 91 93 97 97 98 99 101 102

There are 11 numbers.

The Median is the center value (= the 6th number) = 97.

The mode = highest occurring value = 97.

The mean = sum / 11 = 93.3.

Answer 2

Put the values in order of least to greatest, and then eliminate numbers from each end until you’re left with one.
79, 82, 87, 91, 93, 97, 97, 98, 99, 101, 102
Median - Middle number, 97
Mode - Number that appears most often, 97
Mean - Add all numbers and then divide the total by the number of values in the data set, 93.3
