Assigning test conditions to one group of participants while keeping others neutral to test the effect of a variable under study is a practice in research. The group not assigned test conditions is known as:
Show Hint
Control groups are crucial for reducing confounding variables and ensuring the validity of experimental results.
The control group serves as a baseline in experimental designs and does not receive the experimental treatment. This allows researchers to isolate the effect of the independent variable by comparing the control group with the experimental group.
Example: In drug trials, the control group might receive a placebo while the experimental group gets the active drug.
Purpose: Ensures that any observed effects can be attributed to the independent variable rather than external factors.
