Question

formula of mean mode and median​

Answer 1

mean =sum of all observations /number of observation

mode= n+1/2

median=mo

Answer 2

Easy formulae,

Mean=Sum of all observations/Total observations

Finding the Mode. To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

Median=The median formula is {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” just means the (n)th number. To find the median, you must first order the numbers from smallest to largest. Then find the middle number
