Answer- Let's know about mean first.
Mean- It is the average of some list of numbers.
Mean of single data: Sum of given observations ÷ Total number of observations
Mean of grouped data: There are 3 methods-
a) Direct Method
b) Short-cut or Assumed Mean Method
c) Step-deviation method
Given list of numbers: 7.6, 6.8, 8.5, 9.4, 5.9, 6.4, 9.1 and 4.7
This is a list of single data where
Sum of observations= 58.4
Number of observations= 8
Mean = Sum of observations ÷ Total no. of observations
= 58.4÷8 = 7.3
∴ Mean of given numbers= 7.3
