How do you find the average or mean value?
Average is defined as the sum of all numbers in a group, divided by the count of those numbers. In mathematics, average is the arithmetic mean. It is the central value of the set of numbers. The arithmetic mean is also known as the measure of central tendency. The average of two number, say 2 and 3 is obtained by adding both the numbers (2+3) divided by the number count 2. So the average is (2+3) / 2 = 2.5.
Let us learn here how to find or calculate the average or arithmetic mean value of set of numbers with simple steps.
Average or Arithmetic Mean = Number1 + Number2 + Number3 + ...... / N
N is the total number of data in the given set.
Consider a set of data with even numbers 2,4,6,8,10,12. Find the average mean value of the set of data.
Step 1: Given
Data A = 2,4,6,8,10,12
Total count of Data A = 6
Step 2: Applying values in the formula,
Average or Mean Value = Number1 + Number2 + Number3 + ...... / N
= 2 + 4 + 6 + 8 + 10 + 12 / 6
= 42 / 6
Average = 7
