LESSON: Frequency Tables, Line Plots, and Bar Graphs


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


how often something occurs
information about something or someone-usually in number form
to look at data and draw conclusions based on patterns or numbers
Frequency table
a table or chart that shows how often something occurs
Line plot
Data that shows frequency by graphing data over a number line
Organized data
Data that is listed in numerical order
Bar graph
a way to organize data using bars and two axes. One axis represents the number of each item and the other axis represents the item that was counted.
Double Bar Graph
A graph that has two bars for each item counted. It still uses a scale, but is designed to compare the data collected during two different times or events. A double bar graph is a tool for comparisons.
