The probability density function is f ( x) = 1 b − a for a ≤ x ≤ b. For this example, x ~ U (0, 23) and f ( x) = 1 23 − 0 for 0 ≤ X ≤ 23. Formulas for the theoretical mean and standard deviation are
WebThe cumulative distribution function of a uniform random variable X is: F ( x) = x − a b − a for two constants a and b such that a < x < b. A graph of the c.d.f. looks like this: F (x) 1 X a b WebThe value of the cumulative distribution F (a) marked as an area on the graph of the probability density function, f (x), of a continuous distribution. We can also use the cumulative distribution function to represent probabilities of a certain interval.
