Question

Answer 1

The only possible outlier would be the point 0.8.

An outlier is a value that is far from the rest of the values in a set of data. In this set, the values are not spread out that far. If we had to pick on value, it would be 0.8. 0.8 is the furthest out value in this set.

You can also test the outliers by using the IQR.

Answer 2

Answer: 6, 8.4

Explanation: the y value is furthest away from the x value. 8.4 is 2.4 larger than 6 while other values are only 0.2 or less difference
