What is 90th percentile?

The 90th percentile is a statistical measure used to represent the value below which a certain percentage of observations in a set of data falls. In other words, it is the value that separates the top 10% of data points from the rest.

For example, if a student scores in the 90th percentile on a standardized test, it means that they scored higher than 90% of the other test-takers.

The 90th percentile can be useful in various fields, such as education, healthcare, and finance, to understand where a particular data point ranks in relation to the rest of the data set.

In many cases, the 90th percentile is used as a benchmark to compare individuals or groups, evaluate performance, set standards, and make decisions.
