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

Then, in the table, we look for the Z score of 1. Example 2 SAT scores are distributed normally with mean = 1500 and SD = 300. A friend of yours tells you that she scored in the top 10% on the SAT. What is the lowest possible score she could have gotten? We are looking for ...
Z-scores may be used to do a table lookup for the corresponding percentile in the Normal Table Percentiles for Z-Score table (below). Numbers along the left side (Y-axis) of the table represent the first number and first decimal place of the Z-score, while the numbers along the top (...

The procedure is simple in this case. For a given percentage value value, expressed as a decimal \(p\), which is a number between 0 and 1, we find using Excel or a normal probability table a z-score \(z_p\) so that \[ p = \Pr(Z < z_p) \] ...
