QUANTITATIVE RESEARCH METHOD

What is the primary purpose of survey research?

• To establish cause and effect relationships

• To describe trends, opinions, and attitudes of populations

• To manipulate variables for desired outcomes

• To evaluate the success of qualitative experiments

Which of the following is NOT a type of survey design?

• Cross-sectional survey design

• Longitudinal survey design

• Experimental survey design

• Retrospective survey design

What is a key characteristic of survey research?

• Manipulating variables

• Observing non-numeric data

• Collecting data through questionnaires or interviews

• Analyzing qualitative trends only

How can researchers reduce non-response error in survey research?

• Use a small sample size

• Employ rigorous administration procedures

• Avoid collecting demographic information

• Include only open-ended questions

In survey research, what does the term 'population' refer to?

• The entire world

• A group of individuals sharing a common characteristic

• Only the sample used in a study

• Individuals selected randomly without criteria

What is a pretest in experimental research?

• A statistical analysis after treatment

• A measure before treatment

• A randomly assigned group

• A test of dependent variables

In correlational research, what is the purpose of prediction design?

• To describe two variables' relationships

• To predict an outcome based on one or more variables

• To manipulate variables to test effects

• To assess qualitative feedback

Which of the following is a characteristic of correlational research?

• Control over extraneous variables

• Random assignment of participants

• Use of scatter plots and correlation matrices

• Administration of pretests and posttests

What is a threat to internal validity in experimental research?

• History effects

• Statistical conclusion validity

• Interaction of selection and treatment

• Lack of significant correlation

What distinguishes a 'true' experiment from a 'quasi' experiment?

• The use of scatter plots

• The presence of random assignment

• The lack of pretests

• The absence of control groups
