This article describes the formula syntax and usage of the Z.TEST function in Microsoft Excel. Returns the one-tailed P-value of a z-test. For a given hypothesized population mean, x, Z.TEST returns the probability that the sample mean would be greater than the average of observations in the data set (array) — that is, the observed sample mean.
17 sty 2023 · A one sample z-test is used to test whether a population mean is significantly different than some hypothesized value. A two sample z-test is used to test whether two population means are significantly different from each other. The following examples show how to perform each type of test in Excel.
