About this tool

Calculates the results of a one-sample Z-test, a statistical method used to determine if the mean of a single population sample is significantly different from a known or hypothesized value. Users input necessary parameters, including the sample mean, standard deviation, sample size, and the assumed population mean. The tool then applies the appropriate formula to yield the calculated Z-score and associated probability values, allowing for an assessment of statistical significance. Students studying statistics, data analysts, and researchers performing academic work commonly utilize this calculator. It provides a straightforward way to perform manual calculations related to hypothesis testing without needing specialized statistical software.
