The Normal Distribution Calculator makes it easy to compute cumulative probability, given astandard scorefrom astandard normal distributionor a raw score from any othernormal distribution; and vice versa. For help in using the calculator, read theFrequently-Asked Questionsor review theSample Problems....
Standard normal distribution quantile function (σ =1, μ=0) equates like this: This function is calledthe probit function. The calculator below gives quantile value by probability for the specified through mean and variance normal distribution( set variance=1 and mean=0 for probit function)....
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...

The lognormal distribution is a probability distribution of a random variable whose logarithm is normally distributed. If X is a random variable with a normal distribution, then Y = exp(X) has a log-normal distribution; likewise, if Y is log-normally distributed, then log(Y) is normally ...
