๐ Topic Summary
Dot plots are a simple way to organize and display data using dots above a number line. Each dot represents one observation or data point. They help us quickly see how many times each value occurs in a set of data, making it easy to compare and understand information at a glance. For second graders, dot plots are a great introduction to data analysis and graphing.
Imagine asking your classmates their favorite color. You could make a dot plot to show how many people like each color! The more dots above a color, the more popular it is.
