Exercise: Examine the Effects of Log-transformation on Results

Use what we’ve learned so far to examine the effects of log transformation on results.

We'll cover the following

Let’s test what we’ve learned so far about examining the effects of log transformation on results.

Assignment

Our previous exercise examined the effects of resources and predators on the age at emergence from the water. The data very clearly needed to be log-transformed.

  • What would happen if we don’t log-transform the Age.FromEmergence data?
  • Will we get the same results?
  • What does the Q-Q plot look like in such a case?

Let’s try to find the answers to these questions by plotting the log.Age.FromEmergence variable in this exercise.
