Use Z score calculator to calculate Z score or Z-statistics for hypothesis testing. If you don’t know how to find Z score, use z value calculator (normal distribution).
Refer to the documentation and graphs in our critical value calculator page for more on critical values and regions. Example calculations It is easy to find the Z score corresponding to a given raw score, given that one knows the mean and standard deviation of the normal distribution to which...
