Answer 2

$\huge\mathbb{\purple{MEDIAN \: FORMULA}}$

The formula to calculate the median of the finite number of data set is given here. Median formula is different for even and odd numbers of observations. Therefore, it is necessary to recognise first if we have odd number of values or even number of values in a given data set.

The formula to calculate the median of the data set is given as follow.

$\huge\mathbb{\pink{ODD \: OBSERVATIONS}}$

If the total number of observation given is odd, then the formula to calculate the median is:

Median = {(n+1)/2}thterm

where n is the number of observations

$\huge\mathbb{\pink{EVEN \: OBSERVATIONS}}$

If the total number of observation is even, then the median formula is:

Median = [(n/2)th term

+ {(n/2)+1}th]/2

where n is the number of observations

$\huge\mathbb{\purple{CALCULATING \: MEDIAN}}$

To find the median, place all the numbers in the ascending order and find the middle.

Example 1:

Find the Median of 14, 63 and 55

solution:

Put them in ascending order: 14, 55, 63

The middle number is 55, so the median is 55.
