Uniform Distribution

The uniform distribution, a fundamental concept in probability theory and statistics, characterizes the equal likelihood of any outcome within a specified range. Unlike other probability distributions, where certain values may be more probable than others, the uniform distribution ensures a constant probability for all values in its domain. This mathematical model finds applications in diverse fields, from random number generation in computer science to representing uncertainty in various real-world scenarios. Understanding the uniform distribution is pivotal in statistical analysis, offering a straightforward and unbiased framework for exploring and interpreting uncertain outcomes.
