2nd Quarter Examination Practical Research 2

Which of the following is NOT a quantitative research design?

• A. Experimental

• B. Correlational

• C. Descriptive

• D. Ethnographic

Which quantitative design is best for identifying relationships between two variables without manipulating them?

• A. Experimental

• B. Correlational

• C. Quasi-experimental

• D. Descriptive

A teacher wants to know the average number of hours students spend studying each week. Which design should be used?

• Experimental

• Correlational

• Descriptive

• Quasi-experimental

A researcher wants to test the effectiveness of a new math intervention by comparing test scores between a control group and a treatment group. What is the most appropriate design?

• Descriptive

• Correlational

• Experimental

• Historical

A researcher wants to study the eating habits of senior high school students in Region II. Which sampling procedure is most appropriate to ensure each student has an equal chance of being selected?

• A. Purposive sampling

• B. Convenience sampling

• C. Simple random sampling

• D. Snowball sampling

A study on internet usage among students used convenience sampling by surveying those present in the computer lab. What is the main limitation of this sampling procedure?

• It is too expensive

• It lacks randomness and may not represent the entire population

• It requires complex statistical tools

• It violates ethical standards

A researcher studying academic stress selects 10 top-performing schools and surveys only honor students. Which critique best evaluates the sampling procedure?

• The sample is too large for meaningful analysis

• The sample is biased and may not reflect the general student population

• The sample is ethically inappropriate

• The sample is randomly selected and therefore valid

What does it mean when a research instrument is considered “valid”?

• It produces consistent results over time

• It measures what it is intended to measure

• It is easy to administer

• It has a large number of items

A teacher creates a questionnaire to assess students’ study habits. To ensure reliability, what should the teacher do?

• Ask students if they like the questionnaire

• Administer the questionnaire once and analyze results

• Pilot the questionnaire and check for consistent responses across time or groups

• Include only yes-or-no questions

A researcher develops a 20-item test to measure mathematical reasoning. After expert review, 5 items are removed due to poor alignment with the construct. What aspect of instrument development is being addressed?

• Validity

• Scoring procedure

• Reliability

• Sampling
