Question

Would you expect a scatterplot comparing speed of a car in time it takes to drive 10 miles to show a positive association a negative association or no association explain you’re thinking

Answer 1

If we increase the speed of the car, then the time it takes to drive 10 miles will be less. Therefore, in the scatterplot where the y axis is the speed of a car and the x axis is the time it takes to drive 10 miles, the y value will get lower as x gets higher. This is what we call a negative association.
