MULTIPLE CHOICE QUESTION

To make sure your experiment shows you the usual (or typical) result, you should...

start the experiment as soon as possible.

wait a long time to conduct the experiment.

Answer explanation

If you only do the experiment once, you can't be sure that your results are representative of what usually happens in nature. It's best to do the experiment as many times as you can, so that you get an accurate picture of what the result tends to be (and you can be reasonably sure that your results are not affected by a mistake or an unusual condition).
