Identifying and Graphing Variables

Identify…. If you spend more time studying, then your grade will improve. Independent Variable = Dependent Variable =

Now You Try: If you spend more time studying, then your grade will improve. Independent Variable = amount of time spent studying Dependent Variable = grade

Now You Try: If the temperature of the room is increased, then the bacteria will grow faster. Independent Variable = Dependent Variable =

Now You Try: If the temperature of the room is increased, then the bacteria will grow faster. Independent Variable = temperature of room Dependent Variable = bacterial growth

Organize your data Put your data into a data table Independent Variable __________(unit) Levels Dependent Variable _______________ (unit) Trial 1 Trail 2 Trail 3 mean range

After all of the data from the experiment is collected, then its time to organize the data.

Independent Variable vs. Dependent Variable Also Known As: Manipulated Variable Responding Variable Results: Cause Effect On a graph: X axis Y axis

Step 6: Organize your data Make the data table into a graph GRAPHS make it EASIER to see patterns in the data!

Step 6: Organize your data How do you know what goes on each axis of the graph?

Step 6: Organize your data DRY MIX Dependent Variable = Responding Variable = Y axis Manipulated Variable = Independent Variable = X axis

Parts of a graph Y Axis X Axis

Y Axis (Dependent Variable) X Axis (Independent Variable) Parts of a graph Y Axis (Dependent Variable) X Axis (Independent Variable)
