Question

which of these pairs of variables would you expect to be represented by a scatterplot with a negative correlation? (1 point)
o the depth of the water in a pond and the amount of rainfall
o the number of concert tickets purchased and the number of concert tickets still available for purchase
o the number of miles driven and the number of people on the bus
o a persons height and the persons grade on the math test

Explanation:

• For the depth of water in a pond and rainfall: More rainfall usually leads to greater depth (positive correlation).
• For number of concert tickets purchased and tickets available: As tickets are purchased, available tickets decrease (negative correlation).
• For miles driven and people on bus: No direct logical relation (no clear correlation).
• For height and math test grade: No direct logical relation (no clear correlation).

Answer:

the number of concert tickets purchased and the number of concert tickets still available for purchase
