Z-scores are a measure of how many standard deviations a data point is away from the mean. They are often used to compare data points to each other or to a normal distribution. StatCrunch is a statistical software package that can be used to calculate z-scores.
To find the z-score of a data point in StatCrunch, first enter the data into the software. Then, click on the “Stats” menu and select “Z-Scores.” A dialog box will appear, asking you to enter the mean and standard deviation of the data. Once you have entered this information, click on the “OK” button. StatCrunch will then calculate the z-score for each data point and display the results in a new window.
