Võtitegur

Võtitegur, also known as the coefficient of variation (CV), is a statistical measure used to describe the relative variability of a data set. It is defined as the ratio of the standard deviation to the mean of the data set. The formula for võtitegur is:

CV = (Standard Deviation / Mean) * 100%

The coefficient of variation is a dimensionless number, meaning it does not depend on the unit of measurement. This makes it useful for comparing the relative variability of different data sets, even if they are measured in different units.

A high võtitegur indicates that the data points are spread out over a wide range, relative to the mean. Conversely, a low võtitegur indicates that the data points tend to be close to the mean. A võtitegur of 0 indicates that all data points are identical.

The coefficient of variation is widely used in various fields, including finance, biology, and engineering, to assess the consistency and reliability of data. It is particularly useful when comparing the variability of data sets with different means or units.

In summary, võtitegur is a valuable statistical tool for understanding and comparing the relative variability of data sets. Its dimensionless nature and ease of interpretation make it a popular choice for data analysis and comparison.
