Question 10 • LPISD Earth Systems A - CR

How can scientists best confirm and validate the results of an experiment so they can publish their findings?

Answer
A
by removing the control from the experiment
B
by adding more variables to the experiment
C
by decreasing the number of trials
D
by creating a replicable experiment

Explanation

Scientists can build confidence in experimental results when other researchers can repeat the same procedure and obtain similar results. Creating a replicable experiment makes that confirmation possible. Removing the control, adding variables, or decreasing the number of trials would make the results less reliable, not more so.
