Area Between Two Z-Scores Calculator


The calculator below calculates the area between two Z scores in the standard normal distribution. For example, if you input the values ‘a’ and ‘b’ in the calculator below, it gives the area between these two values. This corresponds to the probability that the random variable lies between ‘a’ and ‘b’.

Area: 0.42122

Note that the total area under the standard normal distribution is equal to 1, with 99.7% of the area lying between the values -3 to 3.
