Mean of Grouped Data

The mean of the observation is the sum of all the values given in the observations divided by the total number of observations.

If y₁,y₂, y₃, y₄...yₙ are observation with respective frequencies f1, f2, f3, f4, ….,fn

Then, the mean of the yof the data is given by:

y¯y¯
=
f1y1,f2y2,f3y3,f4y4,+.....+ynf1,f2,f3,f4,....fnf1y1,f2y2,f3y3,f4y4,+.....+ynf1,f2,f3,f4,....fn

Mode of Grouped Data

The mode of the is that value among the observations which occurs most frequently and is also defined as the value of the observation having a maximum frequency.

Median of Grouped Data

Median is defined as the measure of central tendency which obtains the value of the middlemost observation in the data.

If n is odd, then the median is the

(n+12)th(n+12)th
term of the observations.

If n is even, then the median is defined as the average of the

(n2)th(n2)th
and the
(n+12)th(n+12)th
term of the observations.
