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.μ Mean...
The probability that a score is greater than or equal to the raw score is known as a p-value. Learn more about calculating p-values with ourp-value calculator. Key Properties of a Normal Distribution A normal distribution has several key properties: ...
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...

Example: Finding a z scoreYou collect SAT scores from students in a new test preparation course. The data follows a normal distribution with a mean score (M) of 1150 and a standard deviation (SD) of 150. You want to find the probability that SAT scores in your sample exceed 1380. To ...

The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z. It does this for positive values of z only (i.e., z-values on the right-hand side of the mean). ...
