Question

write the formula for finding mean.median and mode

Answer 1

Mean=sum of all observations/no of observation
Median=if no of obs(n)=even then
(n/2)+(n/2+1)
If n=odd then
(n+1)/2
Mode=frequently occuribg number
Epirical formula for mode is 3median-2mean

Answer 2

formula for mean, median and mode are. as follows=

mean = sum of all observation/ number of observation

mean when frequency is given= sum of the product of frequency and observation/ sum of the product of the frequency.

median when no. of observation is odd = no.of observation + 1 / 2

median when no. of observation is even = (no of observation /2) + (no. of observation /2 + 1/1) /2.

mode = larger frequency occurred no.
or
mode = 3(mean) - 2(median)
