which data set has an outlier?\no 25, 36, 44, 51, 62, 77\no 3, 3, 3, 7, 9, 9, 10, 14\no 8, 17, 18, 20, 20…

Explanation:

Step1: Understand outlier concept

An outlier is a data - point that is significantly different from other data - points in a dataset.

Step2: Analyze first dataset

The dataset (25,36,44,51,62,77) has a relatively smooth increase, no extreme values.

Step3: Analyze second dataset

In the dataset (3,3,3,7,9,9,10,14), the values are in a relatively close range, no extreme outlier.

Step4: Analyze third dataset

For the dataset (8,17,18,20,20,21,23,26,31,39), the value (8) is much smaller than the rest of the values which are mostly in the (17 - 39) range. It is an outlier.

Step5: Analyze fourth dataset

The dataset (63,65,66,69,71,78,80,81,82,82) has a consistent increase, no outlier.

Answer:

(8,17,18,20,20,21,23,26,31,39)
