How to find Average of Data Set?

Average is a number which represents all numbers in the data set. Average and mean are the measures of central tendency in statistics. It is nothing but mean, both refers the same value. These are the easy steps to find the mean of a data sample.

  • First of all, take a data set.
  • Count the number of values in the data set.
  • Add all the values in the data set to get the sum.
  • Divide the sum by count to obtain average.

Mean Formula

Mean of a data set is defined as the sum of all values divided by the size of data set.

mean = xmean = (∑ni=1 xi) / n

Example

Question: Calculate the average of data set {42, 54, 65, 47, 59, 40, 53}?

Solution:

Given data set is {42, 54, 65, 47, 59, 40, 53}

count = 7

mean = xmean = (∑ni=1xi) / n

= (42 + 54 + 65 + 47 + 59 + 40 + 53) / 7

= 360/7

= 51.42

∴ Average = 51.42, sum = 360 and count = 7
