Finding Percentiles

What does "percentile" mean? A percentile is a measure that indicates the value below which a given percentage of observations falls.

For example, if I told you that you scored in the 60th percentile on your ACT test, that would mean that 60% of people who took the test scored less than you. Another way of interpreting this percentile would be that you scored in the top 40% of people who took the ACT.

In this lesson video you will learn how to use the standard normal distribution curve to find percentiles.
