How to fill out z score to percentile

To fill out a conversion table for percentiles to z-scores, follow these steps:

1. Familiarize yourself with the concept: Start by understanding what percentiles and z-scores are. Percentiles represent the relative position of a value within a distribution, while z-scores measure the number of standard deviations an observation is away from the mean.
2. Gather the necessary data: Collect the set of percentiles for which you want to determine the corresponding z-scores. For example, you may have percentiles such as 10th, 25th, 50th, 75th, and 90th.
3. Find the z-score formula: The formula to convert a percentile to a z-score is: z = (x - μ) / σ, where z is the z-score, x is the value corresponding to the percentile, μ is the mean of the distribution, and σ is the standard deviation of the distribution.
4. Calculate the z-scores: Substitute the values of x, μ, and σ into the formula to calculate the z-score for each percentile. For instance, if the mean is 50 and the standard deviation is 10, you can calculate the z-score for the 25th percentile as z = (25 - 50) / 10 = -2.5.
5. Repeat for other percentiles: Continue the calculations for the remaining percentiles using the same formula. This will give you a set of z-scores corresponding to each percentile.
