Rita’s quiz scores are 72, 96, 74,80 and 79. Find the outlier in the data. How does it affect Rita's mean quiz score?

Answer :

The Solution:

Given the data:

[tex]72,96,74,80\text{ and 79.}[/tex]

First, we shall identify the outlier in the given data.

Outliers are data points that are far from other data points. In other words, they're unusual values in a dataset. In this case, the outlier is 96 since other values are in the range of 70 to 80. clearly, 96 is the only value that is outside the range of 70 to 80.
