When researchers inadvertently create a flaw in their experiment that is a threat to internal validity, it is known as a design confound. If these flaws coincide with the experimental manipulation and call into question whether or not the manipulation or the flaws affected the dependent variable, this is known as systematic variability. If the flawed part of the experiment does not coincide with a specific group, and is introduced at random, this is known as __ and does not necessarily pose a threat to internal validity.

1. selection effect

2. random sampling

3. unsystematic variability

4. none of the above

3. unsystematic variability

Explanation:

Unsystematic variability -

It refers to the variability within the individuals or group of people, the type of variability is completely random, i. e., some individual changes in one direction and some in other direction and rest do not change at all, is known as unsystematic variability.

Hence, from the question, the correct term for the given scenario of the question, is unsystematic variability.
