What is outlier in the following set of scores? 12, 13, 12, 2, 9, 12, 14,10, 9

2

Step-by-step explanation:

In a data set, the outlier is the data point that differs significantly from all other data points- it's normally very different from all other points.

In the data set, we can see that all but one of the points are between 9-14.

Hence, we can safely say that the outlier is 2.

To better visualize this, we can plot all the points.

As you can see, all the scores are clumped together, except for "2."

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5
