Hi there!

_______________________

What is Median?

After arranging the given data in the ascending or descending order of magnitude, the value of the middle most observation, is called the median of the data.

Formula to find the median :)

Method : Arrange the data in increasing or decreasing order of magnitude. Let the total number of observation be n.

(i) If n is odd, then median

⇒ Value of $\mathsf{( \frac{n + 1}{2} )\th}$ observation.

(ii) If n is even, then median

⇒ mean of $\mathsf{( \frac{n}{2} )\th}$ and $\mathsf{( \frac{n}{2} + 1 )\th}$ observations.

What is Mean?

The average of a given set of numbers is called the Arithmetic mean, or simply the mean, of the given numbers.

Mean = $\frac{Sum \: of \: observations }{Number \: of \: observations }$

_______________________

Mode : Mode is the most occurring or most frequent number of the data.

Thanks for the question!

Answer 2

:

The Mean

x¯¯¯=∑xN

Here,

∑ represents the summation

X represents scores

N represents number of scores.

The Median

If the total number of numbers(n) is an odd number, then the formula is given below:

Median=(n+12)thterm  

If the total number of the numbers(n) is an even number, then the formula is given below:

Median=(n2)thterm+(n2+1)thterm2

The Mode

The mode is the most frequently occuring score or value.
