Solution
Step 1:
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Step 2
The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.
Step 3
The cost depends on the amount of time a car was parked.
The independent variable is the amount of time a car is parked.
The dependent variable is the cost of parking in dollars.
1 a)
