Question

Calculate the mean value of 70,80,90,60,70,80,100,60,50,60

Answer 1

Mean :
step 1 Address the formula, input parameters & values.
Formula:

µ = n∑i = 0 Xin 
Input parameters & values
x1 = 10; x2 = 20, . . . . , x10 = 100
number of elements n = 10
Find sample or population mean for 10, 20, 30, 40, 50, 60, 70, 80, 90 & 100

step 2 Find the sum for dataset 10, 20, 30, 40, 50, . . . . , 90 & 100

µ = n∑i = 0 Xin
=(10 + 20 + 30 + . . . . + 100)10

step 3 Divide the sum by number of elements of sample or population
=55010
= 55
Mean (10, 20, 30, 40, 50, . . . . , 90, 100) = 55
