Step by step in finding the median of ungrouped data?

Answer 1

Steps:

1.) Arrange the data either ascending or descending order of their values.

2.) Determine the total number of observations, say n.

3.) If the set of number is odd then the middle number will be the median. And if the set of number is even then mean of middle two numbers will be the median.

a.) After that we'll be starting to discuss and give examples on how to find the median of ungrouped data.

Example1:

1.) Find the median of 12, 15, 10, 18, 8.

2.) Arrange the data either ascending or descending order of their values.

8, 10, 12, 15, 18(ascending)

18, 15, 12, 10, 8(descending)

3.) If the set of numbers is an odd integer, find the middle number in the set of numbers.

From the above middle number 12 then 12 is the median.

Example2:

1.) Find the median of 23, 46, 18, 32, 65, 20.

2.) Arrange the data either ascending or descending order of their values.

18, 20, 23, 32, 46, 65(ascending)

65, 46, 32, 23, 20, 18(descending)

3.) If the set of numbers is an even integer, find the two middle numbers in the set of numbers.

From the above we can say that there are two middle numbers

23 and 32. So,

Md = 23+32/2 = 27.5
