To get accurate results in an investigation, what is one thing scientists need to do? Question 3 options: Work with other scientists. Publish their findings. Change the procedures each trial. Repeat the same procedures many times (have multiple trials).
I believe if you repeat the procedure multiple times it gives you the opportunity to double check your results and see if you messed up anything when doing the procedure the first time.
Explanation: repeating the same procedure can show you if anything changes, and can help you catch mistakes along the way rather than immediately showing the world when you could be incorrect.
