For 51 11 21 394145: σ = 197,058.6674
3.898717738 is the standard deviation.
49.30179172 is the standard deviation and 52 is the mean.
If each value in a data set is multiplied by a constant, the standard deviation of the resulting data set is also multiplied by that constant. In this case, since the original standard deviation is 12 points and each value is multiplied by 1.75, the new standard deviation would be 12 * 1.75 = 21 points.
2√(17/21), or about 1.8.
The distribution of x can be almost anything - apart from the Poisson distribution.
3.898717738 is the standard deviation.
The range is 9 and 3.01 is the standard deviation.
49.30179172 is the standard deviation and 52 is the mean.
2√(17/21), or about 1.8.
√2.5
The distribution of x can be almost anything - apart from the Poisson distribution.
The formula for the standard deviation of a sample (s) is given by: s =√(⅟₍n₌₁₎Σ(y-ȳ)²) where y are the data points and ȳ is their mean; it can be rearranged to give: s = √(⅟₍n₌₁₎(Σy² - n((Σy)/n)²) → s = √(⅟₍₅₌₁₎(1815 - 5(⁹⁵/₅)²) → s = √(¼ × 10) → s = √2.5
