Find the area under the normal curve calculator

Enter mean, standard deviation and cutoff points and this calculator will find the area under normal distribution curve.

Please provide any one value to convert between z-score and probability. This is the equivalent of referencing a z-table. Related Standard Deviation Calculator. The z-score, also referred to as standard score, z-value, and normal score, among other things, is a dimensionless quantity that is used to indicate the signed, fractional, number of standard deviations by which an event is above the mean value being measured. Values above the mean have positive z-scores, while values below the mean have negative z-scores. The z-score can be calculated by subtracting the population mean from the raw score, or data point in question a test score, height, age, etc. For a sample, the formula is similar, except that the sample mean and population standard deviation are used instead of the population mean and population standard deviation.

Entrance exam In a college entrance exam, the participants are rated as excellent, very good, good, and fair.

Use this calculator to easily calculate the p -value corresponding to the area under a normal curve below or above a given raw score or Z score, or the area between or outside two standard scores. With mean zero and standard deviation of one it functions as a standard normal distribution calculator a. Alternatively, compute the Z score corresponding to a given probability or quantiles of any normal distribution by its inverse distribution function IDF. This calculator has three modes of operation: as a normal CDF calculator , as a probability to Z score calculator, and as an inverse normal distribution calculator. The first is useful in calculating the probability corresponding to the area under a normal curve below or above a given normal score raw score.
