SUMMATIVE TEST IN PRACTICAL RESEARCH 2

Which research design is best for testing cause-and-effect relationships?

• Descriptive

• Experimental

•  Correlational

• Case Study

A research study aiming to determine relationships between variables is classified as:

• Experimental

•  Descriptive

• Correlational

• Phenomenological

Mixed-methods research is best defined as:

• Combining quantitative and qualitative approaches

• Analyzing only numerical data

• Focusing exclusively on lived experiences

• 1. Using thematic analysis

Which sampling technique ensures every individual has an equal chance of selection?

• Purposive Sampling
  
  

• Simple Random Sampling

• Quota Sampling

• Cluster Sampling

A researcher divides a population into subgroups and randomly selects participants from each subgroup. This is called:

• Stratified Sampling

• Convenience Sampling

• Systematic Sampling

• Snowball Sampling

What is the primary purpose of sampling in research?

• To examine every member of a population

• To draw accurate conclusions about the population
  
  

• To reduce bias in the results

• To measure all variables equally

A valid research instrument ensures:

• Consistent results across trials

• Measurement of what it intends to measure

• Simplicity in administration

• Free from all types of errors

Reliability in a research instrument refers to:

• Ensuring consistent outcomes across tests

• Avoiding pretests

• Addressing biases during data collection

• Using Likert scale-based questions

Pretesting an instrument is primarily done to:

• Reduce the sample size

• Check for clarity and reliability

• Remove biased items

• Avoid errors in statistical analysis

An intervention in research refers to:

• A condition or treatment applied to participants
  
  

• A summary of findings

• Statistical data analysis

• Sampling procedure implementation
