# Larger sets of data

Suppose we want to find the median score achieved by a large number of contestants on a game show. If the scores are presented in order, it would be tedious to rewrite them in order. If the scores were already in order, it could save us time. But if there were a very large number of scores—say thousands, a list would be annoyingly long, whether ordered or not. This is where a frequency table comes in handy. It would be possible to represent thousands of scores in a relatively small table.
