Question

Find the median of the data.
20, 30, 45, 90, 60, 45, 5, 10, 30, 45, 15, 25

Answer 1

Answer: 30

Step-by-step explanation:

On both sides scratch off a number until you get the remaking number. If there is no even number find the middle, ex: two numbers in the middle are 28 and 29. Answer would be 28.5

Answer 2

The median of the given set of data is equal to 30.

In this exercise, you're required to find the median of the given set of data.

Median can be defined as the middle number of a data that has been sorted sequentially. Thus, you should arrange the number in the data in an ascending order and then choose the middle number.

Given the following data;

$x = 20, 30, 45, 90, 60, 45, 5, 10, 30, 45, 15, 25$

When we arrange the data in an ascending order, we have;

$x = 5, 10, 15, 20, 25, 30, 30, 45, 45, 45, 60, 90$

Middle numbers = 30 and 30

Median = $\frac{30 \; + \; 30}{2}$

Median = $\frac{60}{2}$

Median = 30

Therefore, the median of the given set of data is equal to 30.
