📚 Topic Summary
Dot plots are a simple way to organize data using dots above a number line. Each dot represents one piece of data. They help us quickly see how many times each value appears in a set of information. For example, if we asked a group of friends their favorite color, we could use a dot plot to show how many chose red, blue, green, etc. The more dots above a color, the more popular it is!
