Weeks of Saving vs. Money Saved
A student tracks how much money they have after saving the same amount each week. The student saves $20 each week.
Which statement correctly identifies the variables?
A. Money saved is independent because it determines the number of weeks.
B. Number of weeks is independent because it determines the amount of money saved.
C. Both variables are independent.
D. Neither variable is independent.
B: Number of weeks is independent because it determines the amount of money saved.

A coach records the distance a football travels based on the time after it is kicked.
Football Flight: The graph represents the distance traveled by a football at different times after being kicked.
A student says: "Distance is the independent variable because the football's distance changes as time changes."
--> Is the student correct? Explain why or why not.
No. Time is the independent variable because time is the input/change that is being measured first. Distance is the dependent variable because its value depends on the amount of time that has passed.

A vending machine sells drinks for $2 each. The graph shows the total number of dollars collected based on the number of drinks sold.
Two Part Question:
What is the range?
Is the range discrete or continuous?
Range: {0, 2, 4, 6, 8, 10, 12}
The Range is discreet because the outputs occur at specific values based on the number of drinks sold.

A student is studying the relationship between temperature and ice cream sales. They create the following graph.
Ice Cream Sales and Temperature: The relationship between daily temperature and ice cream sales.
A student says: "Ice cream sales are the independent variable because the temperature depends on how much ice cream people buy."
Did the student make a mistake? Explain your reasoning.
The student has reversed the independent and dependent variables.
- Independent variable: Temperature
- Dependent variable: Ice cream sales
Temperature is the factor being used to explain/predict changes in ice cream sales.
