The variance of X is the expected value of X -squared minus the square of the expected value of X.
WebMar 9, 2024 · For continuous random variables we can further specify how to calculate the cdf with a formula as follows. Let X have pdf f, then the cdf F is given by F(x) = P(X ≤ x) = x ∫ − ∞f(t)dt, for x ∈ R. In other words, the cdf for a continuous random variable is found by integrating the pdf.
