Normal Distribution Calculator
Free AppAbout Normal Distribution Calculator
Calculate Normal Distribution probabilities and confidence intervals with ease!
Use this app to calculate the area under a Normal/Gaussian curve (the probability). Just input a Z-score! Also allows users to input different means and standard deviations. Includes options for finding probabilities using one-tail, two-tail and even custom z-scores.
Can also be used to calculate confidence intervals! Just input the probability / significance level and get the confidence interval easily. Also allows user inputted means and standard deviations as well as tail options.

It is surprising how badly designed most statistical apps are. I am very happy that I found this invaluable tool.

It doesn't tell you the probability of a particular value. Other than that it works well.

App is good. It's simple and easy to use. Wish the calculations were more exact though (more decimal places). Also, I did notice that, while "One Tail" option is selected, the inequality sign does not change when you change the option to or from "Above" and "Below". It remains "Pr ( ## < Z ) = " regardless of whether you select the "Above" or "Below" option.

Out of all the normal distribution apps I tried, this was easily the most intuitive, most useful and most well-designed of them all.
