write a mean , mode and median of your class

Answer :

We can understand that by taking an example :

We have data set are 95 , 93 , 91 , 95 , 100 , 99 , 95 and 92 

We arrange it in ascending order  :

91 ,  92  , 93 , 95 ,  95 , 95  , 99 , 100


Mean  = $\frac{91 + 92 + 93 + 95 + 95 + 95 + 99 + 100 }{8} = \frac{760}{8} = \mathbf{95}$


Mode  =  95 ( this number came more than any other number )

And

Median  =  $\frac{{\left({\displaystyle \frac{n}{2}}\right)}^{th} term + {\left({\displaystyle \frac{n}{2}} + 1\right)}^{th} term}{2} = \frac{{\left({\displaystyle \frac{8}{2}}\right)}^{th} term + {\left({\displaystyle \frac{8}{2} + 1}\right)}^{th} term}{2} = \frac{{\left({\displaystyle 4}\right)}^{th} term + {\left({\displaystyle 5}\right)}^{th} term}{2} = \frac{95 +95}{2} = \mathbf{95}$
Similarly you can collect data from your class and find mean , mode and median by yourself and if still have any doubt kindly get back to us , So we can help you precisely .
