To analyze the data
#8
What is the independent variable?
The variable that is measured in an experiment
The variable that is manipulated by the researcher
The variable that is kept constant
The variable that depends on the outcome of the experiment
#9
What is the purpose of random assignment in experimental design?
To ensure that participants are assigned to groups based on their characteristics
To eliminate the need for a control group
To reduce the likelihood of systematic bias or confounding variables
To determine the sample size of the experiment
#10
What is the purpose of blinding in an experiment?

#12
What is the difference between qualitative and quantitative research?
Qualitative research focuses on numbers and statistics, while quantitative research focuses on observations and descriptions
Quantitative research is subjective, while qualitative research is objective
Quantitative research collects and analyzes numerical data, while qualitative research collects and analyzes non-numerical data
Qualitative research is experimental, while quantitative research is observational
#13
What is the purpose of peer review in research?
To ensure that research findings are communicated effectively

An experimental design that involves non-human subjects
An experimental design used in qualitative research
#16
What is the purpose of an Institutional Review Board (IRB)?
To review and approve research proposals involving human participants
To conduct statistical analysis of research data
To recruit participants for research studies
To analyze the data collected from research studies
#17
What is a confounding variable in experimental design?
A variable that is deliberately manipulated by the researcher
A variable that affects the dependent variable but is not the independent variable
A variable that is measured in the experiment
A variable that is kept constant throughout the experiment
#18
What is the purpose of stratified sampling?
To ensure that each subgroup of the population is represented proportionally in the sample
To select participants based on their availability
To randomly select participants from the population
To select participants who meet specific criteria
