Oct 14, 2023 · This is a simple calculator with memory functions similar to a small handheld calculator. Use this basic calculator online for math with addition, subtraction, division and multiplication. The calculator includes functions for square root, percentage, pi, exponents, powers and rounding.

Enter mean, standard deviation and cutoff points and this calculator will find the area under standard normal curve. The calculator will generate a step by step explanation along with the graphic representation of the probability you want to find.

Calculator to find out the z-score of a normal distribution, convert between z-score and probability, and find the probability between 2 z-scores.

Normal Calculator Press to display the horizontal axis tick labels that correspond to the 68%, 95%, and 99.7% inner percentiles within the distributional graph. The horizontal axis labeled x ranges from -3 to 3 in increments of 1 unit.

Specify the mean and standard deviation. Indicate whether you want to find the area above a certain value, below a certain value, between two values, or outside two values. Indicate the value (s). Hit tab, return, or the "recalculate button." The area will be shaded and the size of the area will be shown at the bottom.

Enter the mean μ (average), standard deviation σ, and cutoff points, and this normal distribution calculator will compute the area (probability) under the normal distribution curve.

Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music…

This normal distribution calculator (also a bell curve calculator) calculates the area under a bell curve and establishes the probability of a value being higher or lower than any arbitrary value X.
