Frequency Tables and Line Plots

In this lesson you will learn how to:

• Make a frequency table to organize and display given data.
• Make a line plot given a frequency table.
• Make a frequency table and line plot given unorganized data.
• Collect, organize, display and analyze real-world data using frequency tables and line plots
