The Z score is a measure of how manystandard deviationsa data point is away from the mean. Z scores rely on thestandard normal distribution(or Gaussian) which has a mean of 0 and a standard deviation of 1. It is primarily used to test for differences between means for large samples. ...
To use the calculator, simply input the z-score for the standard normal distribution, select the p-value type, and then click on the "Calculate" button to generate the results. P-Value from Z-Score Calculator Z-score: P-value Type: ...

This free Statistics video tutorial describes how to find the p-value by hand via z-scores. Explains how to use a z-score chart. Works out a couple examples including by hand and also by using a graphing calculator. Makes use of a z-score chart here are
p-value = 2 × min(cdf(x), 1 – cdf(x)) How to Find the P-Value from a Z-ScoreGiven a z-score for a standard normal distribution, you can calculate the p-value using the standard normal distribution formula Φ. p-value = Φ(z-score) ...

When calculating a p-value using the Z-distribution the formula is Φ(Z) or Φ(-Z) for lower and upper-tailed tests, respectively. Φ is the standard normal cumulative distribution function and a Z-score is computed. In this mode the tool functions as a Z score calculator....
but anyway) knows that the z score for 0.05 significance level is roughly 1.64. However, the calculator below can calculate the z score for an arbitrary p-value. It is not that hard if you can calculate the inverse of CDF (cumulative distribution function) for standard normal distribution. ...
