Frequency Distribution

Frequency distribution is a simple (basic, not necessarily easy) type of statistic that people often make into a much bigger deal than it really is. Let's say you are in a class with 100 people, and you have just taken a test. The teacher then tells you that on the test, there were 20 "A"s, 25 "B"s, 35 "C"s, 15 "D"s, and 5 "F"s. What the teacher has just given you is a frequency distribution; a breakdown of how all the scores fell into the different categories or ranges that the overall score was broken into.
