Where, Percentile = (P value × 100) Z-Score: It is a way to compare individuals in a set of data. The score measures how outstanding an individual is relative to the mean of a population (data) using the standard deviation for that population to define the scale. Z-scores may be positive or negative.

However, the major limitation of Z -scores is that they are not straightforward to explain Easy to use calculator for converting a P-value to a Z score using the inverse cumulative probability density function (cumulative PDF) of the normal distribution. Convert P to Z, calculate the standard score (Z-score) from P-value of a normally distributed outcome variable. Percentile to Z score calculator. percentile_to_z: Transform a percentile to a z score. In psycho: Efficient and Publishing-Oriented Workflow for Psychological Science Description Usage Arguments Author(s) Examples The Norm Score Calculator also offers the transformation into z-scores (M = 0, SD = 1), T-scores (M = 50, SD = 10), Standard Values (SW score; a norm scale used in German speaking countries; M = 100, SD = 10), and Wechsler Subscale Scores (M = 10, SD = 3).
