WebOct 31, 2024 · A z-table tells you the area underneath a normal distribution curve, to the left of the z-score. In other words, it tells you the probability for a particular score. To use one, first turn your data into a normal distribution. Then find the matching z-score to the left of the table and align it with the z-score at the top of the table. WebThe normal distribution exists in theory but rarely, if ever, in real life. Histograms provide an excellent graphical display to help us assess normality. We can add a “normal curve” to the histogram which shows the normal distribution having the same mean and standard deviation as our sample.
