source · 
pub fn standard_deviation<'a, T: Clone + Iterator<Item = &'a A>, A>(
    element_iterator: T,
    ddof: usize
) -> f64

Expand description

ddof stands for delta degress of freedom, and the sum of squares will be divided by count - ddof, where count is the number of elements for population standard deviation, set ddof to 0 for sample standard deviation, set ddof to 1
