What is the range of Variable A for the cluster?

to

Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The vertical axis is labeled Variable B. Points are plotted at (one, nine), (one, ten), (two, eight), (two, nine), (three, eight), (three, nine), (three, ten), (four, five), (four, ten), (five, four), (six, two).









2.A company tracked the number of job-related injuries each month. The scatter plot shows the data.

What is the month for the outlier?



Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Time, in months. The vertical axis is labeled Job-related injuries. Points are plotted at (one, two), (two, zero), (three, nine), (four, one), (five, one), (six, three), (seven, two), (eight, one).

Respuesta :

1. The range is the possible values for the y-coordinate in a relation or a set of data pairs.
The range is {nine, ten, eight, five, four, two}

2. If you plot the given points, then you'd see that that point
(three, nine) is far from the rest of the other points which makes it an outlier. Other methods can be used to determine whether or not the point is really and outlier. For now, a visual inspection is enough.
