A random variable is a variable whose value depends on the outcome of a probabilistic experiment. Its value is a priori unknown, but it becomes known once the outcome of the experiment is realized. Definition D
Random Variable Definition A random variable, also known as a stochastic variable, means a collection of possible outcomes and their correspondingprobabilities. In practical use, the meaning ofrandom variablecan be intuitively understood to be a variable that may take on different values randomly but ...
which is 3. A random variable has a set of values, and any of those values could be the resulting outcome, as seen in the example of the dice.2
In statistics, independent variables describe events with outcomes that are independent of each other. An example could be that of two successive coin tosses. What is an example of an independent random variable? An example of independent random variables would be the height of a student and thei...
See Statistics - Continuous Variable ie taking any numerical value in an interval or collection of intervals, via a probability density function that is characteristic of the random variable's probability distribution; or a mixture of both types.

What is a Random Variable? A random variable is a variable where chance determines its value. They can take on either discrete or continuous values, and understanding the properties of each type is essential in many statistical applications. Random variables are a key concept instatisticsand probab...

(This definition holds for continuous variables as well.) A mode of X is a number m such that P(X = m) is largest. This is the most likely value of X or one of the most likely values if X has several values with the same largest probability. For a continuous random variable, a...
