Understanding Outliers

This video tutorial explains the concept of outliers in a data set. An outlier is defined as a number that is significantly different from the other numbers in the set. The tutorial provides an example with a data set where the numbers 35, 37, 39, and 42 are close to each other, but 82 is significantly different, making it an outlier. The video emphasizes that a data set can have more than one outlier, but in the given example, 82 is the only outlier.

• 82

• 35

• 42

Why is the number 82 considered an outlier in the example?

• It is the smallest number

• It is the largest number

• No, only one outlier is possible

In the discussed example, how many outliers are present?
