SampleVariance Command
From GeoGebra Manual
- SampleVariance( <List of Raw Data> )
- Returns the sample variance of given list of numbers.
- Example:
SampleVariance({1, 2, 3, 4, 5})yields a = 2.5.
- SampleVariance( <List of Numbers>, <List of Frequencies> )
- Returns the sample variance of given list of numbers considering the frequencies.
- Example:
SampleVariance({1, 2, 3, 4, 5}, {3, 2, 4, 4, 1})yields a = 1.67.
Hint: If the list in the 
CAS View contains undefined variables, this command yields a formula for the sample variance.
- Example:
SampleVariance({a, b, c})yields \frac{1}{3} a^{2} - \frac{1}{3} ab - \frac{1}{3}ac + \frac{1}{3} b^{2} - \frac{1}{3} bc + \frac{1}{3} c^{2}.
