Answer:
Explanation
of two causes of variation.
Variation can
be defined as any deviation from the specified requirements. It can be either positive

Meaning
of Standard Deviation
·
Calculation
of Standard Deviation with steps
Answer:
Meaning
of Standard Deviation:
Standard
deviation is the root of sum of the squares of deviations divided by the total
number of values given in the dataset. Standard deviation shows the degree of
variation from mean or value expected. A
