2. Graphing Y axis = north to south line dependent variable
x axis = west to east
independent variable

3. Types of graphs Bar: measures comparisons of units Line:
measures changes over time or comparisons over time
Bar:
measures comparisons of units

4. Controlled Experiment
The comparison
Does not go through change during investigation
Always stays the same

5. Independent Variable (X axis)
Variable that stands alone
Never changed by the other variables
The Topics
(Independent variable) causes a change in (Dependent Variable)

6. Dependent Variable (the DATA) Y axis
A variable that is depended by another to measure the amount of change
the variable that changes by something
It isn't possible that (Dependent Variable is measured. It does not cause a change in the (Independent Variable).

7. Warm up 8/12-13 What is an Independent variable?
