Question

The data below shows the attendance of fans at each home game for the high school baseball team. Fan attendance at home games: 34, 37, 30, 65, 34, 38, 41, 33 Calculate the average attendance with and without the outlier. A. Average Attendance with the outlier: B. Average Attendance without the outlier: (Round to the nearest thenth) Question 1 options:

Answer 1

Average attendance with outlier = 39

Average attendance without outlier = 35.3

Explanation:

Given the following data 34, 37, 30, 65, 34, 38, 41, 33

The outlier is the value that is lower or higher than other values in the dataset. Hence the outlier in this case is 65

Average = Sum of data/sample size

With the outlier;

Sum of dataset = 34+37+30+65+34+38+41+33

Sum of datasets = 312

Sample size = 8

Average attendance with the outlier = 312/8

Average attendance with the outlier = 39

Without the outlier;

The required data will exclude 65;

34, 37, 30, 34, 38, 41, 33

Sum of data = 34+37+30+34+38+41+33

Sum of data = 247

Sample size = 7

Average attendance without outlier = 247/7

Average attendance without outlier = 35.3
