Standard DEVIATION
Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.
It is the estimate for s, the sample standard deviation.
Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.
No. Not at all. Whoever told you that fails statistics forever.
Standard DEVIATION
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.
Standard deviation in statistics refers to how much deviation there is from the average or mean value. Sample deviation refers to the data that was collected from a smaller pool than the population.
mean deviation is minimum
Yes.
Standard deviation is a measure of how spread out a set of numbers are from each other. It has a variety of uses in statistics.
Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.
It is the estimate for s, the sample standard deviation.
Usually s means standard deviation of a sample.
Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.
The mean and standard deviation. If the data really are normally distributed, all other statistics are redundant.
No. Not at all. Whoever told you that fails statistics forever.
