Question

The value in a data set that is different from all other values of the data set is called .

Answer 1

Consider the data set for the number of states visited by students as follows:


In the given data, all the values lies within the range of $0$ to $6$, except for $18$ which is quite larger from the other values. Thus, $18$ is said to be the outlier of this data set.

Hence, a value in a data set that is very different from all other values of the data set is called an outlier.
