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

It would reduce the significance of any single measurement error.

It would make calculations easier.

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

It would make a plant’s death less of an issue.

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.

the answer is "a.) well–developed vascular system."
