How to Convert Between Z-Scores and Percentiles in Excel
March 30, 2020 - It turns out that a z-score of 1.78 corresponds to a percentile of roughly 96.2. In plain English, this means a data value that has a z-score of 1.78 is larger than roughly 96.2% of all other data values in the dataset. We can use the following built-in Excel function to convert a percentile to a z-score:

r/googlesheets on Reddit: How to convert percentile to Z-score?
January 15, 2020 -
So I have data sets from the CDC that include a formula to calculate a variety of statistics for a given age using a given Z-score, but for my project it would be much easier if I could input a percentile and get the results for that percentile. How can I convert a percentile into its corresponding Z-score?

January 15, 2020z-score percentile for normal distribution
Where on earth do the z-scores on this table come from? they're values of the inverse of the cdf (quantile function) for a standard normal distribution https://en.wikipedia.org/wiki/Normal_distribution#Quantile_function Say I wanted to get the z-score for the 1.5th percentile. Is this doable? Sure, any decent stats package will have it. For example in R it would be qnorm(1.5/100) which gives -2.17009. You can even get it from Excel (e.g. see normsinv) Many numerical libraries offer either this function directly or the erf-1 function from which it can be obtained. Is there a formula somewhere for calculating these? Yes and no. If you want a simple closed form formula there isn't one. There are numerous approximations, but they're not really ideal for writing down easily; they're designed to be accurate as well as reasonably fast on computers but they're not designed for dealing with by humans; there are a bunch of approximations given in a number of papers.

July 31, 2016Getting percentile from z-score
Yes, there most definitely is. The function you want is the normal cumulative distribution function (cdf) NORMSDIST if you already have the z-score. If you don't want to convert to z-score first, you can also use NORMDIST with the info you used to find the z-score. More on reddit.com

April 4, 2020Help calculating a percentile from a Z-score
There's little value out that far, since essentially nothing is close enough to normal for those numbers to be accurate. For what purpose do you need these values? when you say "percentiles" are you actually looking for the cdf, the ccdf (survivor function), the two-tailed area - outside (-6,6) and (-12,12) - or what? The upper tail areas (ccdf) are: > pnorm(c(6,12),lower.tail=FALSE) [1] 9.865876e-10 1.776482e-33 More on reddit.com

February 17, 2021What is a Z-score?
A Z-score (or standard score) measures how many standard deviations a data point is from the mean. It's calculated as: Z = (X - μ) / σ, where X is the value, μ is the mean, and σ is the standard deviation.

What is a confidence interval?
A confidence interval is a range of values that likely contains the true population parameter. For example, a 95% confidence interval means we're 95% confident the true value falls within that range. Z-scores help calculate these intervals.

For instance, the 84th percentile corresponds to a Z Score of 1, meaning that 84% of the data points in a dataset fall below the value with a Z Score of approximately 1. The Percentiles to Z Score Chart typically includes two columns: Percentile and Z Score. By using this chart, you can quickly determine the Z Score associated with a given percentile and vice versa.

Although this function is still available for backward compatibility, you should consider using the new functions from now on, because this function may not be available in future versions of Excel. For more information about the new functions, see PERCENTILE.EXC function and PERCENTILE.INC function. ... If k is non-numeric, PERCENTILE returns the #VALUE! error value. If k is < 0 or if k > 1, PERCENTILE returns the #NUM! error value. If k is not a multiple of 1/(n - 1), PERCENTILE interpolates to determine the value at the k-th percentile.
