Presentation transcript:

A picture is worth a thousand words. Graphs A picture is worth a thousand words.

There are many different types of graphs : line, bar, pie

What is this graph about?

The independent variable is always at the bottom on the x axis The independent variable is always at the bottom on the x axis. The dependent variable is always at the side on the y axis.

Pie graphs show percentages.

Line graphs show changes over time.

Bar graphs compare.

Let’s practice. Number your paper to five and use the graphs to answer the following questions.

1. What food has the most sugar. 2 1. What food has the most sugar? 2.What percentage of sugar does it have?

3. What is the least popular music?

4.How many students ate potatoes on Thursday?

5.What does the value of Sarah’s car do over time?

Data tables The first column in a data table is the independent variable. The second column in the table is the dependent variable. Where on a graph does the independent variable go? The dependent variable?

What is the independent variable for the table?

Use the graph paper provided to graph this data.

Turn your graph paper around and graph this data.
