median

Hello students, in this blog we are going to read the How to Find Median. Median is the very important concept that comes under in statistics and probability. In the statistics it comes under the measure of the central tendency. Median divides the number series into two equal parts. In any number list the middle number from the number list is the median. For example we have number series 1, 2, 3, 4, 5, 6, 7 so the median will be 4. To calculate the median (read here for more) the following steps should be consider in mind, that are: -
-List of numbers should be finite.
-The numbers should be arranged in ascending order.
-If the given number list is odd then the median will be the number that is coming in the middle.
-If the given number list is even then the median will be calculated by taking two middle number's average.
Let’s take some example to understand the median more.
Example 1: - Find the Median for 14, 11, 18, 20, 28 and 29.
Solution: - Given the set of numbers are: 14, 11, 18, 20, 28, 29
Arrange the numbers in an ascending order 11, 14, 18, 20, 28 and 29
The given set has an even number of value.
So the median will be the average of two middle numbers.
The average of two number is (18 + 20)2 = 38 / 2 = 19.
So the median is 19.
Example 2: - Find the Median for 11, 34, 14, 18 and 29.
Solution: -The given set of numbers: 11, 34, 14, 18, 29
Arrange the numbers in the ascending order 11, 14, 18, 29, 34
The given set has an odd number of values.
So the middle number will be the median.
The center number is 18
So the median is 18
