AnswER ✍️

✏ Mean :

In a statistical frequency data , Mean is abbreviated as average of the data in a group or table ,

$\blacksquare\:\:\footnotesize{Mean=\dfrac{Total \:Value \:of \:the\:data}{Total\:no.\: frequency }}$

✏ Mode :

In a statistical group frequency data , the class or the subject which repeats the most often times i.e., which have a higher frequency than the other is known as mode of that data .

E.g,

Let's in an experiment of tossing 100 coins 56 times heads come and 30 times tails whereas 4 times didn't give any result .

here you can see that Heads have more frequency than the other which is 56 ,

therefore here the mode is Heads (56).

✏ Median :

In a statistical group frequency data , often it's to be needed to find out the median of a group data ,

For single data

if , n= be the frequency of the data , then

•Case 1 ( n= odd)

median term = $\dfrac{n+1}{2}'th$ term.

•Case 2 ( n= even)

median terms = $(\dfrac{n}{2})'th$ & $(\dfrac{n}{2}+1)'th$ terms
