In any normal distribution, we can find the z-score that corresponds to some percentile rank. If we're given a particular normal distribution with some mean and standard deviation, we can use that z-score to find the actual cutoff for that percentile. In this example, we find what pulse rate represents the top 30% of all pulse rates in a The figure illustrates the percentile rank computation and shows how the 0.5 × F term in the formula ensures that the percentile rank reflects a percentage of scores less than the specified score. For example, for the 10 scores shown in the figure, 60% of them are below a score of 4 (five less than 4 and half of the two equal to 4) and 95% are To find the corresponding Z Score, consult the Percentiles to Z Score Chart and locate the percentile value closest to 72. In this case, the closest value is 72, which corresponds to a Z Score of 0.583. This means that the data point falls 0.583 standard deviations above the mean. The Percentiles to Z Score Chart is an essential tool in the By Zach Bobbitt May 7, 2021. To find the percentile of a z-score on a TI-84 calculator, you can use the following syntax: normalcdf (-99, z-score, μ, σ) where: μ = population mean. σ = population standard deviation. To access this function on a TI-84 calculator, simply press 2nd then press VARS then scroll down to normalcdf ( and press ENTER. Z-scores measure how outstanding an individual is relative to the mean of a population using the standard deviation for that population to define the scale. Note that percentiles use the median as the average (50th percentile), while z-scores use the mean as average (z-score of 0).
