TASK 1
1.
a)
Mean = Sum / Number of observation
= 4702 / 115
= 40.8
Interpretation: The above mean value indicates the average and most common age of UK Netflix
viewers in the collection of data.
b)
Range = Maximum – Minimum
65 = 80 – Minimum
Minimum = 80 – 65 = 15
Interpretation: The above value indicates that minimum of 15 age of subscribers are UK Netflix
viewers.
c)
Standard deviation = √ variance
= √163.4
= 12.8
Interpretation: This indicate 12.8 dispersion of dataset in relative to its means and average.
d)
Coefficient of variation = Standard deviation / mean
= 12.8 / 40.8
= 0.3
Interpretation: The above value indicates lower coefficient of variation which further means that
there is lower level of dispersion around the mean. The coefficient of variation below 5% sounds
good (Clifto and Clifton, 2019).
