Question

How could increasing the number of plants help you decrease error in the experiment? Check all possible reasons.

Answer 1

Having more data would make the average height less affected by one or two plants that are randomly shorter or taller.

Answer 2

Answer: Increasing the number of plants in an experiment will help decrease the error, because you have more test subjects to run the test on.

Explanation:

The more subjects that you have have the more tests you can run, this will give you a chance to get more accurate and consistent results. When completing an experiment, you normally have to run 5 or more tests in order to get a goos set of data. So by increasing the number of plants you test on, you'll be able to get a better set of data.
