Question

what are the formulas for finding the mean, median and mode??????????????????????????

Answer 1

Mean=sum of observations/no.of observations
Median,if the no.of observations are even then the formula is n/2,n/2+1,if they are odd then the formula is n+1/2
Mode means the mostly repeated observation ,there is no separate formula to find mode.
Mean=[3*median-mode]/2.

Answer 2

mode is the most occuring number in an observation
mean is the sum of observations divided by total number of observation
median is the middlemost value of observation
MEAN
 

Here,
∑, represents the summationX, represents scoresN, represents number of scores.
MEDIAN


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

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