Scaled Score to Percentile
Scaled Score to Percentile for a given Standard Distribution


In the first slot you need introduce the scaled score you are going to use to get its percentile.
In the second slot, you need to introduce the maximum value of the scale of your scaled scores. For example, if you are working with school exams, the maximum value for a school exam is 100, so you need to introduce 100 into the first second slot. EXAMPLE: If I want to calculate the percentile of 80, in a scale that goes from 0 to 100, then I need to introduce 80 into the first slot, and 100 into the second slot. If I want to calculate the percentile of 3, in a scale that goes from 0 to 10, then I need to introduce 3 into the first slot, and 10 into the second slot. This calculator can help you when preparing your AP Statistics test. Using a scaled score to percentile calculator you can explore and analyze the data and infere patterns. To ensure you are ready on time for the examination, you should check out the AP Statistics tutor available in this website, as well as the AP Statistics online course that are offered.

If you are preparing for the AP Statistics exam and are interested in converting the scaled score into percentiles you should use this score distributions. Besides this scaled score calculator, you can find conversion charts online, like this psychometric conversion chart that might be helpful. This other document can give more information not just on the results, but on the process to get those results. There are documents more specifics, that might help you if you are trying to interpret the results of school tests and evaluations. This is a good source to interpret scaled scores and percentiles. However, as you can see there many resources online to find out about conversions between scaled scores and percentiles. Use them wisely, since they can be confusing and sometimes overwhelming. Most of those resources are focus on the education and psychometric field. Interpretation of results in this field can be very tricky, and an expert is actually needed to have an accurate interpretation of the results. Using this calculator, you understand that scaled scores can have different distributions, and that this calculator calculates your percentile following a Standard Distribution, in particular, the same distribution than a tscore follows. The results may be not accurate depending on the kind of distribution of your sample. You use this calculator as it is. This results are an approximation, is your responsibility to check the accuracy of this results.
