1. Which of the following is a characteristic of quantitative research?

• Focuses on subjective meanings

• Uses statistical tools for analysis

• Conducted in naturalistic settings
  
  

• Relies on narrative data

A study that investigates the relationship between hours of study and test scores is an example of:

• Experimental research

• Correlational research

• Descriptive research

• Case study

In an experimental research design, the variable that is manipulated is called the:

• Dependent variable

• Independent variable

• Control variable

• Extraneous variable

Which design focuses on comparing the same group of participants at multiple time points?

• Cross-sectional design

• Longitudinal design

• Correlational design

• Experimental design

The primary purpose of descriptive research is to:

• Determine cause-and-effect relationships

• Explore relationships between variables
  
  

• Describe characteristics of a population

• Test a hypothesis

A sampling method where every member of the population has an equal chance of being selected is called:

• Convenience sampling

• Random sampling

• Stratified sampling

• Snowball sampling

What is the primary advantage of stratified sampling?

• It reduces the sample size.
  
  

• It ensures representation of all subgroups.

• It eliminates sampling bias completely.

• It simplifies data collection.

Which sampling technique is most appropriate for a hard-to-reach population?

• Purposive sampling

• Snowball sampling

• Cluster sampling

• Systematic sampling

A researcher selects every 5th student from a list of 100 students. This method is known as:

• Random sampling

• Systematic sampling

• Stratified sampling
  
  

• Cluster sampling

The group that a researcher wishes to generalize their findings to is called the:

• Sample

• Population

• Stratum

• Cluster
