Task 1
a) The mean
Sum = 4972
Total sample size = 113
Mean = Sum / sample size
= 4972 / 113
= 44
The result shows that average age of Netflix viewer is around 44 years.
b) Standard Deviation
Standard deviation = √ variance
= √166.7
= 12.91
The standard deviation result shows that total variance between viewers age varies by 12.91.
c) Coefficient of variance
Coefficient of variance = standard deviation / mean
= (12.91 / 44) × 100
= 29.34%
The result shows that on an average the age of viewers are deviated from mean by 29.34%. This
indicates that most of the viewers have age around 44 years.
