The correct option is
D 0In the given data set, except
19, all the remaining data points lie in between
0 to
10. So, the outlier of the given data set is
19.
On arranging the data points with outlier in increasing order, we get
Median with outlier= Mean of
8th and 9th data points
=3+32=3
Given ordered data set without outlier:
Median without outlier= Central value of the data set
=3
So, we get
∙ median with outlier=
3
∙ median without outlier=
3
∴Median with Outlier−Median without outlier=3−3=0, i.e., option (d.) is the correct one.
Note:––––––– For the given data set, an outlier does not shift the median.
