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

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

Also Known
As:
Manipulated

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
