Organizing and displaying data are important in statistics. After data are collected, the data may not make sense just looking at them.
That is why it is important to organize and display the data using tables or graphs.
Here you will learn how to organize and display quantitative and qualitative data using bar graphs, pie graph, histograms, polygons, and stem-and-leaf display.
