Probability Density Function Calculator Cumulative Distribution Function Calculator Quantile Function Calculator Basic Probability Calculators. In mathematics, probability and statistics are related to each other but are different concepts. For example, Our life is full of probabilities. Statistics are often related to probability because we use much of the data in determining the possible outcomes. Statistical analysis often uses probability distributions.

Enter probability or weight and data number in each row: This calculator can help you to calculate basic discrete random variable metrics: mean or expected value, variance, and standard deviation. Mean or expected value of discrete random variable is defined as. Variance of random variable is defined as. An alternative way to compute the variance is. The positive square root of the variance is called the standard deviation.

## The Poisson random variable is 4. The average rate of success is 3. Here, we define a "success" as a school closing. Since the schools have closed historically 3 days each year due to snow, the average rate of success is 3. Therefore, we plug those numbers into the Poisson Calculator and hit the Calculate button. The calculator reports that the
