Question

Which relationships could have a negative correlation? Select three options. number of hours on video games and test scores speed of a car and minimum stopping distance average running speed and total race time adult’s head circumference and age outside temperature and amount of a heating bill

Answer 1

Answer:

- number of hours on video games and test scores

- average running speed and total race time

- outside temperature and amount of a heating bill

Step-by-step explanation:

1. number of hours on video games and test scores (negative correlation - as you spend more hours on video games, test scores might decrease)

2. speed of a car and minimum stopping distance (positive correlation - as the distance to the next stop increases, the speed of the car should increase)

3. average running speed and total race time (negative correlation - as you run for longer, your speed should decrease)

4. adult’s head circumference and age (positive correlation - as your age increases, your head size increases, too)

5. outside temperature and amount of a heating bill (negative correlation - as temperature increases, the heating bill decreases)

Answer 2

The two options with negative correlations are:

"Number of hours on video games and test scores" and "Outside temperature and amount of a heating bill"

Which relationship could have a negative correlation?

A relation between two variables, x and y, has a negative correlation when if one variable increases, the other decreases.

From the options, the ones that can have a negative correlation are:

Number of hours on video games and test scores: Here as the number of hours that you play video games increases, it is possible that your test scores decrease, so we have a negative correlation.

Outside temperature and amount of a heating bill: As the outside temperature decreases, the amount that you pay in heating increases, so again, we have a negative correlation.
