If a data set is normally distributed, a particular data point’s z-score can tell us what percentage of the data falls below that data point via the cumulative z-table. phifer performance plus
Z-Score: Formula, Examples & How to Interpret It Outlier
WebA z score of −2.5 is two-and-a-half standard deviations below the mean and is therefore farther from the center than both of the previous scores, and a z score of 0.25 is closer than all of the ones before. In Unit 2, we will learn to formalize the distinction between what we consider “close to” the center or “far from” the center. Web5 nov. 2024 · A z score of 2.24 means that your sample mean is 2.24 standard deviations greater than the population mean. Step 2: Find the p value To find the probability of your … Web1.
