#1
What is factorial design in experimental research?
A design where two or more independent variables are manipulated
ExplanationManipulation of multiple independent variables.
#2
Which of the following is a benefit of factorial designs?
They allow researchers to study interactions between variables
ExplanationFacilitates study of variable interactions.
#3
In a 2x2 factorial design, how many conditions are there in total?
4
ExplanationTotal conditions in a 2x2 design.
#4
What is a factorial design?
A design where two or more independent variables are manipulated
ExplanationManipulation of multiple independent variables.
#5
What does a 2x2 factorial design signify?
Two independent variables with two levels each
ExplanationTwo variables, each with two levels.
#6
What is a main effect in factorial designs?
The effect of one independent variable while ignoring the other variables
ExplanationEffect of one variable disregarding others.
#7
In a 2x3 factorial design, how many independent variables are there and how many levels does each variable have?
2 independent variables with 3 levels each
ExplanationTwo variables, each with three levels.
#8
What is a full factorial design?
A design where all possible combinations of levels of the independent variables are tested
ExplanationTesting all possible variable combinations.
#9
What is an interaction effect in factorial designs?
When the effect of one independent variable depends on the level of another independent variable
ExplanationDependency of one variable's effect on another.
#10
What is a fractional factorial design?
A design where only a fraction of all possible combinations of levels of the independent variables are tested
ExplanationTesting only a fraction of possible variable combinations.
#11
What is the advantage of using a fractional factorial design?
It requires fewer participants and resources
ExplanationEfficient use of resources and participants.
#12
What is a confounding variable in factorial designs?
A variable that is not manipulated but affects the dependent variable
ExplanationNon-manipulated variable affecting dependent variable.
