#1
What is factorial design in experimental research?
A design where only one independent variable is manipulated
A design where two or more independent variables are manipulated
A design where dependent variables are manipulated
A design where participants are randomly assigned to groups
#2
Which of the following is a benefit of factorial designs?
They simplify data analysis
They allow researchers to study interactions between variables
They reduce the need for randomization
They are only applicable in laboratory settings
#3
In a 2x2 factorial design, how many conditions are there in total?
#4
What is a factorial design?
A design where only one independent variable is manipulated
A design where two or more independent variables are manipulated
A design where dependent variables are manipulated
A design where participants are randomly assigned to groups
#5
What does a 2x2 factorial design signify?
Two independent variables with two levels each
Two independent variables with one level each
Two dependent variables with two levels each
Two dependent variables with one level each
#6
What is a main effect in factorial designs?
The interaction between independent variables
The effect of one independent variable while ignoring the other variables
The effect of dependent variables
The effect of randomization
#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
2 independent variables with 2 levels each
3 independent variables with 2 levels each
3 independent variables with 3 levels each
#8
What is a full factorial design?
A design where all possible combinations of levels of the independent variables are tested
A design where only one independent variable is manipulated
A design where only one dependent variable is measured
A design where participants are not randomized
#9
What is an interaction effect in factorial designs?
When independent variables have no effect on the dependent variable
When the effect of one independent variable depends on the level of another independent variable
When dependent variables interact with each other
When randomization fails
#10
What is a fractional factorial design?
A design where only one independent variable is manipulated
A design where only a fraction of all possible combinations of levels of the independent variables are tested
A design where dependent variables are manipulated
A design where participants are randomly assigned to groups
#11
What is the advantage of using a fractional factorial design?
It requires fewer participants and resources
It ensures all possible combinations of independent variables are tested
It simplifies data analysis
It eliminates the need for replication
#12
What is a confounding variable in factorial designs?
A variable that is not manipulated but affects the dependent variable
A variable that is manipulated and affects the dependent variable
A variable that is manipulated and affects the independent variable
A variable that is not relevant to the study
