Experimental Design Principles

Question 1 • LPISD Earth Systems A - CR

Which part of experimental design is most important to a scientist when replicating an experiment?

Answer
A
having exactly the same data as the previous experiment
B
using the same procedure and variables as the previous experiment
C
conducting an experiment similar to the previous experiment
D
using the same laboratory that was used in the previous experiment

Explanation

To replicate an experiment, a scientist should follow the same procedure and control or measure the same variables. This makes it possible to check whether the original results can be reproduced. The data do not need to be exactly the same, and the experiment does not have to be done in the same laboratory.
