Learning Goals:
I can construct appropriate graphs (bar, pie, scatterplot, line graph) to communicate different types of scientific data clearly and effectively.
I can analyze and interpret data displayed visually in charts, diagrams, and graphs in order to draw conclusions and make evidence-based evaluations.
I can identify independent and dependent variables, recognize trends/patterns in data sets, and understand how to display relationships between quantities using graphs.

Experimental Data
Data Tables:
Good data tables can easily be understood without any additional information.
Trouble spots are a lack of complete titles (main title, column titles, and units).
Use metric (SI) units as much as possible.
All data that is collected should be recorded in the data table.
1. Main Title- describes what the table is showing; usually describes a relationship between the independent and dependent variables.
2. Independent Variable - the factor that you change or the factor that is the control. Variables of time are often the independent variable, however, not always. Include any applicable units with the title of the column in the table, instead of next to each number. Placed on the x-axis of the graph (line or bar).
3. Dependent Variable - the factor that changes in response to the independent variable. This is what you are testing and measuring. Include any applicable units with the title of the column in the table, instead of next to each data point. Placed on the y-axis of the graph (line or bar).
Graphs:
A good graph can be understood without any additional information.
Shows the information from the data table in a visual form.
Show units in axes titles and use a key if multiple lines or bars are presented on the graph.
1. Main Title - should be transferred from the data table.
2. Independent Variable - displayed on the x-axis.
3. Dependent Variable - displayed on the y-axis.
Types of Graphs:
Bar - used to compare different or similar things.
Line - used to show how one thing changes (often over time, but not always).
Pie - displays of different things make up a whole (100%).
Analyzing Data (table or graph):
Briefly describe the data.
Indicate any relationships, patterns, or trends between the independent and dependent variables.
If mathematical operations were used to produce the data, include this in your descriptions.
Identify the graph that matches each of the following stories.
I had just left home when I realized I had forgotten my books so I went back to pick them up.
Things went fine until I had a flat tire, but I was soon back on the road.
I started out calmly, but sped up when I realized I was going to be late.
