Mean: 89 customers
Median: 88 customers
Mode: no mode
The first thing that should be done when finding the key features of a data set is rearranging the numbers from least to greatest.
66, 73, 76, 78, 80, 82, 87, 89 90, 92, 97, 101, 110, 125
Let's proceed to finding the mean, median, and mode.
The mean of a data set is calculated by finding the sum of all values in the set and then dividing by the number of values in the set. In this case, there are 14 values in the set.
Substitute values
Add terms
Calculate quotient
To identify the median, we observe the middle value. 66, 73, 76, 78, 80, 82, 87 | 89 90, 92, 97, 101, 110, 125 Dang it! There is no middle value. When this happens, we need to calculate the median by finding the average of the two values closest to the middle. When arranged from least to greatest, 87 and 89 are the most central values. Median=87+ 89/2=88
The mode of a data set is the value that occurs most frequently. 66, 73, 76, 78, 80, 82, 87, 89 90, 92, 97, 101, 110, 125 In this set, each number occurs only once. Therefore, there is no mode.
