Question

1) In each scenario below, specify each variable as a response variable, an explanatory variable, or neither.

a. A researcher collects measurements of VO2 max and resting heart rate on a group of
subjects to study the relationship between these two variables.

b. A real estate agent wants to be able to predict selling prices of houses in Vancouver. He
collects data on 100 recently sold houses, recording their selling prices, size, age, number
of bedrooms, and whether they had a suite.

c. A physicist is investigating particle decay rates. She conducts a series of experiments,
recording in each the number of remaining particles at each time point.

Explanation / Answer

Question 1

(a) Here response variable - Resting heart rate

Explantory Variable - VO2 Max

(b) Response variable - seling price of house

Explantory Variable - Selling price, SIze, age, number of bedrooms or whether they had a suite or not.

(c) Here

the number of remining particles at each time point is not a explantory variable neither a resonse variable.
