02

Concept

Centre: can be described by selecting a value that divides the observations in half, with the bigger half taking greater values and the smaller half taking lower values.

03

Explanation

The center can be described by simply determining the value that splits the observations in half, with one half taking a higher value and the other half taking a lower value. The median of the distribution is this value. There are 50possible values, and the median is determined by adding the averages of the 25thand 26thvalues, which is 13.3%Hence, option (a) is correct
