Question

13, 19, 17, 14, 16, 15, 18, 20 Find the data median​

Answer 1

Answer:

16.5

Step-by-step explanation:

Median is the middle value of a data.

First, we arrange the values in ascending order.

13, 14, 15, 16, 17, 18, 19, 20

The given data has 8 terms, hence an even number. Therefore, the median will be the average of $\frac{n}{2}$ and  $\frac{n}{2}$ + 1 term where n is the number of terms, i.e. 8

So the $\frac{n}{2}$ term is 8/2 = 4th term

and  $\frac{n}{2}$ + 1 term is 8/2 + 1 = 4 + 1 = 5th term

The 4th term is 16 and the 15th term is 17

The average of 16 and 17 is 16.5
