Graph probability density function
WebJul 24, 2024 · The term probability distribution function is kind of ambiguous, since there are a number of ways to quantify the probability distribution of data. I will provide a link the Wikipedia page for the probability density function, but essentially its integral over a given range gives you the probability of that range. Probability Density Function ... Web14.6 - Uniform Distributions. Uniform Distribution. A continuous random variable X has a uniform distribution, denoted U ( a, b), if its probability density function is: f ( x) = 1 b − a. for two constants a and b, such that a < x < b. A graph of the p.d.f. looks like this: f (x) 1 b-a X a b. Note that the length of the base of the rectangle ...
