The normal distribution calculator to finding the probability less than $1.5$, probability greater than $1.5$, probability less than $1$, probability greater than $1$ and probability between $1$ and $1.5$ with a mean of $0.5$ and standard deviation of $2$. For any other values, just su...
Normal distribution calculator finds probability, given z-score; and vice versa. Fast, easy, accurate. Online statistical table. Sample problems and solutions.
Normal Distribution CalculatorEnter the raw score, mean, and standard deviation to find the probability of getting a number above or below that score using the normal distribution calculator below. Mean (μ): Standard Deviation (σ): Raw Score (x): ...
Enter the mean and standard deviation for the distribution. Enter the chosen values of x1 and, if required, x2 then press Calculate to calculate the probability that a value chosen at random from the distribution is greater than or less than x1 or x2, or lies between x1 and x2. ...
This distribution calculator determines the Cumulative Distribution Function (CDF), scores, probabilities between two scores, and PDF or PMF for the following distributions: Normal, Binomial, Student's t, F, Chi-Square, Poisson, Weibull, Exponential, and Uniform. ...

This normal distribution calculator (also a bell curve calculator) calculates the area under a bell curve and establishes the probability of a value being higher or lower than any arbitrary value X. You can also use this probability distribution calculator to find the probability that your variable...
A normal distribution probability table (found in the appendix of most introductory statistics texts).In the examples below, we use Stat Trek's Normal Distribution Calculator to calculate probability. In the next lesson, we use normal distribution probability tables. Normal...

The standard normal distribution, also called the z-distribution, is a special normal distribution where the mean is 0 and the standard deviation is 1.Any normal distribution can be standardized by converting its values into z scores. Z scores tell you how many standard deviations from the mean...
