Attached are two trials that were run comparing time and the length of an icicle. These were run with different settings and with different rates of water. Compare and contrast the lines of best fit and answer the following questions.
1. For each trial:
Does the data appear to be linear? Explain how you can know
How long do we expect the icicle to be after five hours in each of the two different trials?
How accurate do you expect those answers to be if we compared them to the actual icicle length after five hours?
How much time would we have to wait if we wanted the icicle to be 100 cm long?
2. Give an example of data that might appear highly correlated but where the independent variable would not actually be causing the change in the dependent variable.
