Depending on what your distribution represents, start by either writing the formula for the raw score of a population: $$ x = \mu + z{\sigma} $$, or the formula for the z-score of a sample: $$ x = \bar{x} + zs $$, Substitute in values for this problem (z-score, mean, and standard deviation) into the formula: $$ x = 133 + (3)(18) $$, Range, Standard Deviation, and Variance Calculator, 5 Number Summary Calculator / IQR Calculator, Standard Deviation Calculator with Step by Step Solution, Outlier Calculator with Easy Step-by-Step Solution, What is a Z-Score? is a normalized score that will allow you to compare values relative to their population. Using the percentile, we can find the relative position of a certain value in our range. My answers are not matching the predefined hidden answers of the test cases. The expression in this step is simply a rewrite of the z-formula. . This corresponds to a z-score of . In any normal distribution, we can find the z-score that corresponds to some percentile rank. How do I find a percentage with only the mean and standard deviation? WebZ-Score to Percentile Calculator Instructions: This Z-Score to Percentile Calculator will compute the percentile associated to a Z-score that is provided by you, and a graph will be shown to represent this percentile. The table below is intended for.
