Uniformijakaumat

Uniformijakaumat, often translated as uniform distribution, is a fundamental concept in probability and statistics. It describes a situation where every possible outcome of a random variable has an equal chance of occurring. This means that within a given range, the probability of observing any specific value is constant.

There are two main types of uniform distributions: discrete and continuous. A discrete uniform distribution applies to a finite set of outcomes. For example, when rolling a fair six-sided die, each number from 1 to 6 has a probability of 1/6. A continuous uniform distribution applies to a range of real numbers. In this case, the probability density function is constant over the interval. For instance, if a bus arrives at a station every 10 minutes, and you arrive at a random time, the probability of the bus arriving within any 1-minute interval is the same.

The uniform distribution is often used as a baseline model when there is no reason to believe that any outcome is more likely than another. It serves as a starting point for understanding more complex probability distributions and is widely applied in simulations, random number generation, and various statistical analyses.
