#1
What is the purpose of a variable in research?
To store and manage data
To execute operations
To display output
To design experiments
#2
What is sampling in research?
The process of selecting a subset of individuals or objects from a larger population
The process of analyzing data
The process of designing experiments
The process of reporting research findings
#3
What is a population in research?
The group of participants who receive the experimental treatment
The entire group of individuals or objects that the researcher is interested in studying
The group of participants who do not receive the experimental treatment
The group of participants who administer the experiment
#4
What is the purpose of a research design?
To select the appropriate statistical analysis for a study
To manipulate variables to achieve desired outcomes
To plan and structure the overall research process
To analyze and interpret data collected in a study
#5
In research design, what does 'dependent variable' refer to?
A variable that is manipulated by the researcher
A variable that is measured and expected to change
A variable that remains constant
A variable that influences the independent variable
#6
What is a confounding variable in research?
A variable that is irrelevant to the study but affects the results
A variable that is manipulated by the researcher
A variable that is measured and expected to change
A variable that remains constant
#7
What is the difference between qualitative and quantitative variables?
Qualitative variables are measured numerically, while quantitative variables are descriptive.
Qualitative variables can only take on specific values, while quantitative variables can take on a range of values.
Qualitative variables are continuous, while quantitative variables are categorical.
There is no difference between qualitative and quantitative variables.
#8
What is a control group in an experiment?
The group of participants who receive the experimental treatment
The group of participants who do not receive the experimental treatment
The group of participants who administer the experiment
The group of participants who evaluate the experiment
#9
What is reliability in research?
The extent to which a study's findings can be generalized to other populations
The degree to which a measurement tool produces consistent results
The degree to which a study accurately measures what it intends to measure
The extent to which a study minimizes bias
#10
What is a continuous variable in research?
A variable that can only take on specific values
A variable that is measured in discrete units
A variable that can take on any value within a certain range
A variable that is manipulated by the researcher
#11
What is a null hypothesis in research?
A hypothesis that there is no relationship between variables
A hypothesis that there is a significant relationship between variables
A hypothesis that there is a causal relationship between variables
A hypothesis that there is an indirect relationship between variables
#12
What is a moderator variable in research?
A variable that influences the dependent variable
A variable that influences the relationship between the independent and dependent variables
A variable that remains constant throughout the study
A variable that is irrelevant to the study
#13
What is the purpose of randomization in research experiments?
To ensure all participants have equal chances of being assigned to different groups
To ensure that participants are aware of the experiment's objectives
To manipulate variables to achieve desired outcomes
To reduce the complexity of the research design
#14
What is internal validity in research?
The extent to which study findings can be generalized to other populations
The degree to which a study accurately measures what it intends to measure
The degree to which a study minimizes bias
The extent to which a study's design ensures that observed effects are due to the manipulation of the independent variable
#15
What is external validity in research?
The degree to which a study accurately measures what it intends to measure
The extent to which study findings can be generalized to other populations
The extent to which a study minimizes bias
The extent to which a study's design ensures that observed effects are due to the manipulation of the independent variable
#16
What is a mediator variable in research?
A variable that influences the dependent variable
A variable that influences the relationship between the independent and dependent variables
A variable that remains constant throughout the study
A variable that is irrelevant to the study
