What is a Probability Density Function (PDF)?
Probability Density Function Calculator: A Probability Density Function, or PDF, is a statistical function that describes the likelihood of a continuous random variable taking on a particular value. Unlike a probability mass function, which applies to discrete variables, a PDF is used for continuous variables and shows the probability of a value falling within a particular range. The PDF does not provide a probability for a single point but rather the density over an interval.

Understanding Probability Density Calculations
In probability theory, calculating density functions involves using integrals to find the area under the curve of the distribution over a given interval. For example, in a normal distribution, the probability density of a value is calculated using the Gaussian function. These calculations are essential in fields like physics, finance, and data science where predicting probabilities over continuous intervals is necessary.
