Variation signaled by individual fluctuationsVariation signaled by individual fluctuations or patterns in the data is called
A. special or assignable causes
B. common or chance causes
C. explained variation
D. the standard deviation

Coefficient of Variation and Standard Deviation are two measures of dispersion or spread among the data values.
Let's say we have two different sets of data.
Explain which of the two mentioned measures can more accurately find which of these two data sets have more spread or variability in their data values.
