Question

Write the formula of mean, median and mode for classify data.
​

Answer 1

Answer:

Mean= Sum of observation/number of observation

for eg: find the mean of following data- 10,11,12,13,14

Mean= Sum of observation/total observation= 60/5= 12

The mean is 12.

Median is the middle value of the whole data.

eg) Find the median of 2,4,5,7,9

Here the median is 5 as it is the middle value of the data.

In case,there is even set of data then there is a specific formula : two middle number /2

So in 2,4,5,7,8,9 the median is

5+7/2 = 12/2= 6.

Here median is 6.

Mode= Highest frequency in the given data

Mode is the value appearing most number of times.

eg) In the given date: 1,2,3,4,6,6,7,10

The mode is 6 since it has appeared twice(highest frequency).
