AP PSYCHOLOGY

Detailed explanation-1: -An extraneous variable is any variable that you’re not investigating that can potentially affect the dependent variable of your research study. A confounding variable is a type of extraneous variable that not only affects the dependent variable, but is also related to the independent variable.

Detailed explanation-2: -An extraneous variable is any variable not being investigated that has the potential to affect the outcome of a research study. In other words, it is any factor not considered an independent variable that can affect the dependent variables or controlled conditions.

Detailed explanation-3: -Participant variables: These extraneous variables are related to the individual characteristics of each study participant that may impact how they respond. These factors can include background differences, mood, anxiety, intelligence, awareness, and other characteristics that are unique to each person.

Detailed explanation-4: -Anything that is not the independent variable that has the potential to affect the results is called an extraneous variable. It can be a natural characteristic of the participant, such as intelligence levels, gender, or age for example, or it could be a feature of the environment such as lighting or noise.

Detailed explanation-5: -An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. Example 1: Solve for x, 1x − 2+1x + 2=4(x − 2)(x + 2) .
