3. What Kinds of Data Do Line Graphs Display? Pg. 40
To help see what data mean you can use a graph.
A graph is a “picture” of your data.
One kind of graph is a line graph. Line graphs display data that show how one variable (the responding variable) changes in response to another variable (the manipulated variable).
Scientists control changes in the manipulated variable. Then they collect data about how the responding variable changes.
A line graph is used when a manipulated variable is continuous, which means there are other points between the tested ones.

9. Why are Line Graphs Powerful Tools? Pg. 44
A line graph in which the data points yield a straight line is a linear graph.
The kind of graph in which the data points do not fall along a straight line is called a nonlinear graph.
Both kinds of line graphs are useful.
How are they useful?
they allow you to identify trends, make predictions, and recognize anomalous data.
Graphs make it easy to see anomalous data points. When a graph does not have any clear trends, it probably means that the variables are not related.

10. Fig 3 Graphs in Science Linear Trends
Data plotted in a line graph may show a trend. Is the graph linear or nonlinear? What is the graph’s trend?

11. Fig. 4 Graphs in Science Data Variation
Even though some points do not fall on the line, this graph shows a trend. What is the anomalous data point?

15. Scientific Inquiry Developing a Hypothesis
Offer two hypotheses for why the student's digital music player stopped working.

16. Scientific Inquiry Design and Conduct an Experiment
Identify the independent variable, the dependent variable and the other two variables in this experiment. Think about a hypothesis for this experiment.

17. Scientific Inquiry Collecting and Interpreting Data
A data table helps you organize the information you collect in an experiment. Graphing the data may reveal any patterns in your data.

18. Scientific Inquiry Drawing Conclusions
Sometimes the same experiment can have very different data.
