A z-score greater than 0 represents an element greater than the mean. A z-score equal to 0 represents an element equal to the mean. A z-score equal to 1 represents an element that is 1 standard deviation greater than the mean; a z-score equal to 2, 2 standard deviations greater than...
The idea is to a percentile to z score conversion table, which is essentially using a standard normal distribution table. This can also be achieved by using Excel. If conversely what you have is a z-score, you can use ourz-score to percentile calculator. Or you may be interested incomput...
Standard deviation calculator; Normal distribution calculator; and Empirical rule calculator. IQ percentile The percentile of a score is the percentage of people who score equal to or below the score. For example, an IQ score of 70 is in the 2nd percentile (for SD = 15), which means that ...
