Probability Density Function Calculator
The Probability Density Function Calculator helps you calculate the probability of an event occurring at a given point for a normal distribution. By entering the mean and standard deviation of the distribution, you can determine the value of the PDF at a specific point.

What is a Probability Density Function Calculator?
The Probability Density Function (PDF) Calculator is a tool to compute the value of the probability density function for a normal distribution. It uses the mean (μ) and standard deviation (σ) of the distribution to calculate the probability that the random variable equals a given value (X).
Formula for Probability Density Function
The formula for the probability density function of a normal distribution is:
f(x) = (1 / (σ * √(2π))) * e^(-0.5 * ((x - μ) / σ)^2)
Advantages and Disadvantages of Using the Probability Density Function Calculator
Advantages:
- Quick and accurate calculation of PDF for normal distributions.
- Helps visualize the behavior of data in terms of probability for specific values.
- Useful for statistics, data analysis, and probability theory.
Disadvantages:
- Assumes data follows a normal distribution, which may not always be the case.
- Does not account for skewed or bimodal distributions.
