Confounders include environmental factors, neglected differences between subjects, and unexpected changes during the experiment.
For example, a scientist working with lab rats might not concern herself whether the lab rats in her study are kept in room A or room B of the laboratory. But at the end of the experiment, she might notice that the lab rats in room A are significantly fatter than those in room B.
Whatever the case, a good scientist knows the potential sources of limitations and mentions those influential ones in her paper.
A scientist’s toolbox is as strong as its weakest link.
Regardless, she will likely cite the environment as a confounder, letting other scientists know that future studies should keep the lab rats in the same room.
Having obtained a Master of Science in psychology in East Asia, Damon Verial has been applying his knowledge to related topics since 2010.
A scientist often notices a confounder only during or after the experiment.
She lists that confounder as a limitation in her report.
While you can use a microscope to view a two-dimensional image of bacteria and record results from that image, you won’t be able to record the height of the bacteria.
If one thing you are reporting in your study is the volume of bacteria, you will have to estimate the height and multiply it by the observed area to get a volume.
