Uniform Probability Distribution Definition

One of the simplest density curves is for a uniform probability distribution. In probability theory and statistics the continuous uniform distribution or rectangular distribution is a family of symmetric probability distributions.

Standard deviation by the basic definition of standard deviation example 1 the current in ma measured in a piece of copper wire is known to follow a uniform distribution over the interval 0 25.

Uniform probability distribution definition. Updated march 08 2019 a discrete uniform probability distribution is one in which all elementary events in the sample space have an equal opportunity of occurring. The continuous uniform distribution on an interval of r is one of the simplest of all probability distributions but nonetheless very important. A deck of cards has within it uniform distributions because the likelihood of drawing a heart a club a.

The uniform distribution on an interval is a special case of the general uniform distribution with respect to a measure in this case lebesgue. Features of the uniform distribution the uniform distribution gets its name from the fact that the probabilities for all outcomes are the same. In statistics a type of probability distribution in which all outcomes are equally likely.

We have already seen the uniform distribution. These are normally plotted as straight horizontal lines. Every one of n values has equal probability 1 n.

Uniform distribution is defined as the type of probability distribution where all outcomes have equal chances or are equally likely to happen and can be bifurcated into a continuous and discrete probability distribution. The distribution describes an experiment where there is an arbitrary outcome that lies between certain bounds. Uniform distributions are very common for initial studies of probability.

In particular we have the following definition. Unlike a normal distribution with a hump in the middle or a chi square distribution a uniform distribution has no mode. The bounds are defined by the parameters a and b which are the minimum and maximum values.

The interval can be either be closed or open. The uniform distribution corresponds to picking a point at random from the interval. In particular continuous uniform distributions are the basic tools for simulating other probability distributions.

As a result for a finite sample space of size n the probability of an elementary event occurring is 1 n. From wikipedia the free encyclopedia redirected from uniform distribution discrete in probability theory and statistics the discrete uniform distribution is a symmetric probability distribution wherein a finite number of values are equally likely to be observed. Therefore the distribution is often abbreviated u where u stands for uniform distribution.

Calculate the mean variance and standard deviation of the distribution and find the. Find the formula for the probability density function of the random variable representing the current.
