Question

how to find the median of 12,15,18,19,21
​

Answer 1

Answer:

Median of the data = 18

Step-by-step explanation:

Given numbers 12,15,18,19,21

To find,

The median of the numbers

Solution:

Median is the middlemost value of a data set. It is calculated by writing the observations in the ascending order

Given data is 12,15,18,19,21

The ascending form of the data is 12,15,18,19,21

There are 5 observations in the data.

The middlemost value of the data is the third observation in ascending order

here, the third observation = 18

Hence median of the data = 18

Answer 2

Answer:

Median : 18.

Step-by-step explanation:

Given : numbers 12,15,18,19,21.

To find: The median of the given numbers.

Solution :

For finding median of any given numbers, we have to arrange the numbers in ascending or descending order at first.

This  set of numbers are are called ungrouped data, where the frequency distribution is not given.

Median : Median is the middle most value of the given data or set of numbers. I t is one of the measures of central tendency.

If the data is odd, then median will be the middle value.

If the data is even, then the median will be the average of the middle two values. The median can also be defined as the value which separates the higher half of the data and the lower half of the data.

Here, the given set of data is arranged  in ascending order and the data is of odd in number. So we can find the median .

18 is in the middle of the given set of numbers.

Median = 18.
