Line plot

A line plot:

A ) 4
B ) 2
C ) No outlier
D ) 7

Steps to derive

1 The number of times information value occurs in the information set is indicated by cross marks above the respective information value on the number line.
2 Information item that is far apart from the remainder of the information is called an outlier.
3 In the line plot, they notice that the information values are close to each other.
4 So, there is no outlier in the line plot.
