Enter mean, standard deviation and cutoff points and this calculator will find the area under normal distribution curve. Normal distribution or Gaussian distribution (named after Carl Friedrich Gauss) is one of the most important probability distributions of a continuous random variable Normal distribution calculator. Enter mean (average), standard deviation, cutoff points, and this normal distribution calculator will calculate the area (=probability) under the normal distribution curve. The z-score is the number of standard deviations from. In addition it provide a graph of the curve with shaded and filled area.

The calculator allows area look up with out the use of tables or charts. The area represents probability and percentile values. This calculator determines the area under the standard normal curve given z-Score values. In Microsoft Excel or Google Sheets, you write this function as =NORMINV (0.99,1000,50 Normal Distribution Calculator to Find Area, Probability From our normal distribution table, an inverse lookup for 99%, we get a z-value of 2.326. You can use the normal distribution calculator to find area under the normal curve Rearranging this formula by solving for x, we get: x = μ + zσ. It takes 4 inputs: lower bound, upper bound, mean, and standard deviation. The normal distribution calculator works just like the TI 83/TI 84 calculator normalCDF function.
