Median, 1.5

Answer 1

A) Median, 1.5

Explanation:

Since we have given that the collected data as follows:

| 2 | 14 | 1 | 2 | 0 | 1 | 0 | 2 |

As we know that there are three measures of central tendency.

1) Mean is given by

2) Media of 0, 0, 1, 1, 2, 2, 2, 14 is given by

3) Mode of 0,0,1,1,2,2,2,14 = 2as 2 is occurring most of the times, but we know that median is the best measure to find the center. Hence, Median is the best measure and its value is 1.5.

Answer 2

The best answer is:  "2" ;  which is the "mode".
