Use this calculator to compute the z-score of a normal distribution.

Some of the more commonly occuring Z transforms are shown below. Delta function, step, ramp, parabola, power, exponent, sine, cosine and damped sine and cosine functions.

This transformer calculator helps you to quickly and easily calculate the primary and secondary full-load currents of the transformer. It also determines the turns ratio and type of transformer. User Instructions: Select the number of phases from the drop-down menu; Enter the transformer rating and select the appropriate unit. The z-score is the number of standard deviations a data point is from the population mean. You can calculate a z-score for any raw data value on a normal distribution. When you calculate a z-score you are converting a raw data value to a standardized score on a standardized normal distribution.

What is z-score?

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.), then dividing the difference by the population standard deviation:

where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The z-score has numerous applications and can be used to perform a z-test, calculate prediction intervals, process control applications, comparison of scores on different scales, and more.

Z-table

A z-table, also known as a standard normal table or unit normal table, is a table that consists of standardized values that are used to determine the probability that a given statistic is below, above, or between the standard normal distribution.

The table below is a right-tail z-table. Although there are a number of types of z-tables, the right-tail z-table is commonly what is meant when a z-table is referenced. It is used to find the area between z = 0 and any positive value, and reference the area to the right-hand side of the standard deviation curve.
