Exponential Distribution: the probability distribution that describes ... one of the data sets is normally distributed. Probability Density Function: a function of a continuous random variable, such ...

So far, you learned about discrete random variables and how to calculate or visualize their distribution functions. In this lesson, you'll learn about continuous variables and probability density ...

As with discrete random variables, it is sometimes convenient to work with probabilities directly and sometimes to work with cumulative probabilities. The probability density function (pdf) describes ...

A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous ... distribution function of a random variable ...

The probability density function of a uniform random variable looks like a horizontal line segment over the support. This indicates that for any interval of a given length within the support, the ...

Let $X$ be a continuous random variable. A probability density function (pdf) $f(x)$ is an integrable function where \[\int\limits_a^b f(x) \mathrm{d} x = \mathrm{P ...

when the return is seen as a random variable. Probability distributions are characterized as either discrete or continuous, and as working as either a probability density function, or a cumulative ...
