Chapter 42-3 Chasing Ghosts

[Gnex]

I know this is a stupid question but what's a control he said he left one guy as a control. I assume he was normal

A control is like your base.

So you would have 1 person who you would just leave normal.....

Then on the others you experiment.... give one Drug A + Drug B, give another Drug A + Drug C, etc... etc....

It is a way to measure what exactly is making the changes/ and what the changes are.....


Here is an example.....

An example of an experimental control might be testing plant fertilizer by giving it to only half the plants in a garden: the plants that receive no fertilizer are the control group, because they establish the baseline level of growth that the fertilizer-treated plants will be compared against. Without a control group, the experiment cannot determine whether the fertilizer-treated plants grow more than they would have if untreated.
