Question

McKenna is performing an experiment. She is testing the relationship between the temperature of water, and how long it takes for rust to form on iron plates. If she finds that higher temperatures lead to lower times for rusting, what is the qualitative relationship?positive correlationno correlationnegative correlationinverse square correlation

Answer 1

As with the increase in the temperature, the time taken to form the rust on the iron plate decreases.

This correlation is known as a negative correlation.

Thus, the relationship between the temperature of the water and the time taken to form rust on the iron plate is a negative correlation.

Hence, the third option is the correct answer.
