Graphing Review

Graphing Review

Practice reading and analyzing graphs so you ace the reassessment!

There are lots of parts of a graph

• Title

• X-Axis Label

• Y-Axis Label

• Scales

• Legend

Title

• Tells you what the graph is about

• Includes the dependent and independent variables

X-Axis Label

• Tells you what the x-axis (horizontal/bottom line) is showing

• Independent Variable

• Matches the different trails in the experiment

X-Axis Label

This experiment looked at how leaving a piece of chalk in a cup of vinegar over time would change the weight of the chalk. The independent variable is the time, on the x-axis.

Multiple Choice

In an experiment to determine the effects of listening to loud music on test scores, what would the x-axis label be?

• Type of music

• Test score

• Volume of music

• Grade in class

Multiple Choice

What is the independent variable based on the graph?

• Favorite candy

• Type of candy

• Popularity

• How many people hate it

Y-Axis Label

• Tells you what the y-axis (vertical line) is talking about

• Dependent variable

• What we measure/collect data on

Y-Axis Label

In the chalk-vinegar experiment, the mass of the chalk was measured. That makes it the dependent variable, on the y-axis.

Multiple Choice

In an experiment to determine the effects of listening to loud music on test scores, what would the y-axis label be?

• Volume of music

• Type of music

• Number of people

• Test score

Multiple Choice

What is the dependent variable based on the graph?

• Popularity

• Type of candy

• Time of trick-or-treating

• Number of trick-or-treaters

Trends in Graphs

• Talk about how one variable changes the other

• As the [independent variable] increases, the [dependent variable] ...

Trends in Graphs

As the time increases the mass of chalk decreases.

Trends in Graphs

As time increases, the speed increases.

Multiple Choice

Describe the trend shown in the graph.

• As the volume decreases, the mass stays the same.

• As the mass decreases, the volume increases.

• As the volume increases, the mass increases.

• As the mass increases, the volume stays the same.

Multiple Choice

Describe the trend in rainfall from January to June in City 1.

• As time increases, the monthly rainfall increases.

• As time increases, the monthly rainfall decreases.

• As time decreases, the monthly rainfall stays the same

• As time decreases, the monthly rainfall decreases.

Time to go take the reassessment!
