### Introduction

## 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

## Vocabulary

- Frequency

- Data

- Frequency table
- a table or chart that shows how often something occurs

- 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.
