From the normal curve table, the z-score that is closest to 40% (the area from the negative z-score to the mean) is -1.28. Since the z-score is a representation of the number of standard deviations, the 10th percentile is approximately 1.28 standard deviations below the mean.

Calculate the z score with the value of percentile and the tail of distribution like left-tailed, right-tailed, two-tailed and confidence level. Code to add this calci to your website. Just copy and paste the below code to your webpage where you want to display this calculator.

Z-scores can be used to find percentile rank (Raw score ~ Z-score ~ Percentile rank) If the distribution is normal, Z=0 means a Median percentile (50th, 50 percent of the distribution falls below the mean) if you score 33 points and an average of 24, you will get a spread score of 9. From the given data set, 10th number is 85. Therefore, 80th percentile of given data set is 85.

For a given percentile \(p\), which is a number between 0-1, finding the corresponding z-score is done by finding the value of \(z^*\) that solves the following: \[ p = \Pr(Z z^*) \] How do we find such \(z^*\)? 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.
