Continuous Uniform PDF:
From: | To: |
The continuous uniform distribution is a probability distribution where all intervals of the same length are equally probable. It's defined by two parameters: the minimum (a) and maximum (b) values.
The calculator uses the uniform distribution probability density function:
Where:
Explanation: The probability density is constant between a and b, and zero elsewhere.
Details: The uniform distribution is fundamental in probability theory and is used when all outcomes are equally likely, such as in random number generation.
Tips: Enter the lower bound (a) and upper bound (b) values. The upper bound must be greater than the lower bound.
Q1: What's the difference between continuous and discrete uniform distribution?
A: Continuous uniform distribution applies to continuous variables over an interval, while discrete applies to a finite set of distinct values.
Q2: What are common applications of uniform distribution?
A: Used in simulations, random sampling, and as a prior distribution in Bayesian statistics when no prior information is available.
Q3: What is the mean of a uniform distribution?
A: The mean is (a + b)/2, the midpoint of the interval.
Q4: What is the variance of a uniform distribution?
A: The variance is (b - a)²/12.
Q5: Can the bounds be negative?
A: Yes, the bounds can be any real numbers as long as b > a.
