WebFeb 27, 2024 · Follow these steps to calculate the kth percentile: 1. Rank the values. Rank the values in the data set in order from smallest to largest. 2. Multiply k by n. Multiply k (percent) by n (total number of values in the data set). This is the index. You'll refer to this in the next steps as the position of a value in your data set (first, second ... WebA positive Z-score means that raw score is above the mean. In addition to its position above or below the mean, a Z-score also communicates that score’s distance from the mean in terms of how many standard deviations away it is. For example, with a mean of 65 and standard deviation of 3, the raw score 59 can be converted into a Z-score.
