The probability distribution of a random variable X tells what the possible values of X are and how probabilities are assigned to those values A random variable can be discrete or continuous . A discrete random variable X has a countable number of possible values. Example: Let X Random Variables. Formally, a random variable is a function that assigns a real number to each outcome in the probability space. Define your own discrete random variable for the uniform probability space on the right and sample to find the empirical distribution.

Discrete random variables A. In a great many situations, only a limited set of numbers can occur as values of a random variable. Quite often, the set of numbers that can occur is relatively small, or at least finite in extent. For example, suppose I randomly draw a page from the statistics book and note the page number. In this instance, the values of the random variable are all of the Since all random variables are divided into discrete and continuous random variables, we have end up having both discrete and continuous joint probability distributions. These distributions are not so different from the one variable distributions we just looked at but understanding some concepts might require one to have knowledge of multivariable calculus at the back of their mind.

In this case, it is no longer sufficient to consider probability distributions of single random variables independently. One must use the joint probability distribution of the continuous random variables, which takes into account how the distribution of one variable may change when the value of another variable changes.

Continuous random variables Discrete data is data that is finite or countable, such as the number of soft-centred chocolates in a box of soft- and hard-centred chocolates. A continuous random variable assumes an uncountable or infinite number of possible outcomes between two values. That is, the variable can assume any value within a given range. For example, the birth weights of babies and In this case, it is no longer sufficient to consider probability distributions of single random variables independently.
