Recall that the percentile of a given value tells you what percent of the data falls at or below that given value. So for example, the 30th percentile can be thought of as the cutoff for the "bottom" 30% of the data. Often, we are interested in the "top" instead of the "bottom" percent. We can connect this idea to percentiles. For example, the 30th percentile would be the same as the cutoff for the top 70% of values. Suppose that the 88th percentile on a 200 point exam was a score of 146 points. This means that a score of 146 points was the cutoff for the top Submit Question percent of exam scores.
