Find the mean of the first five whole numbers

Find the mean of the first five whole numbers.

Answer: whole numbers are non-fractional numbers. They are a set of positive integers and zero. The whole number set is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ………}. All numbers, including zeros, are true and do not include fractions or decimals. 3/4, 2.2, or 5.5 is not an integer. Therefore, these are not integers. In addition, subtraction, multiplication, and division operations are applicable for all numbers.

Now, according to the definition first five whole numbers are 0, 1, 2, 3, 4

Sum of all the observations (Σxi) = 0+1+2+3+4 = 10

Number of observation (n) = 5

Mean = Σxi /n

            = 10/5 = 2
