Normal distribution calculator finds probability, given z-score; and vice versa. Fast, easy, accurate. Online statistical table. Sample problems and solutions.
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. ...
mean of normal distribution andstandard deviationto find the corresponding probabilities. More precisely, this Guassian distribution calculator help us to find: probability less than a $X_1$, probability greater than a $X_1$, probability less than a $X_2$, probability greater than a $X_2$ ...
Enter 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): Probabilities:...
A standard normal distribution table, like the one below, is a great place to check the referential values when building confidence intervals. You can use our normal distribution probability calculator to confirm that the value you used to construct the confidence intervals is correct. For example,...
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. ...
