Calculator to find out the z-score of a normal distribution, convert between z-score and probability, and find the probability between 2 z-scores.
Free Standard Normal Distribution Calculator - find the probability of Z using standard normal distribution step-by-step.
Find the percentage of values below a given z-score in a standard normal distribution.
The Normal Distribution Calculator makes it easy to compute cumulative probability, given a standard score from a standard normal distribution or a raw score from any other normal distribution; and vice versa.
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.
For any practical use, instead of tables, you can use the normal distribution calculator Simply select the appropriate value from "Probability (p) or percentile (𝑥)": 𝑥₁ for the Z-table or P(X≤𝑥₁) for the inverse Z-table.
Normal Distribution Calculator. Use this calculator to easily calculate the p-value corresponding to the area under a normal curve below or above a given raw score or Z score, or the area between or outside two standard scores.
Use this Z table calculator to easily calculate the Z-score from a given raw score. Also computes areas under the normal curve ( p -values) cut off by a given score. A table of Z scores and corresponding p-values is included, as well as the z score formula.
In hypothesis testing, the standard normal distribution is used to calculate the test statistic. Numerical summaries calculator with steps. Solve the mean, median, mode, variance, standard deviation, covariance, correlation coefficient and more.
Z-Score Calculator can be used for any type of Z-Score-related calculations. You can enter a raw score (X), Population mean ( μ), and Standard Deviation (σ) in the first calculator to find the Z-Score with steps and related probabilities to that row score.
