Mar 30, 2020 · How to Convert Percentiles to Z-Scores in Excel. We can use the following built-in Excel function to convert a percentile to a z-score: =NORM.S.INV(probability) where: probability = the percentile you’re interested in converting. For example, here is how to convert a percentile of 0.85 to a z-score: It turns out that a percentile of 0.85 corresponds to a z-score of roughly 1.036. In plain English, this means a data value located at the 85th percentile in a dataset has a z-score of 1.036.

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

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