Answer Key: 1. a) To ensure that the instrument measures what it intends to measure accurately and consistently 2. b) The degree to which a research instrument measures what it is intended to measure 3. a) A survey designed to measure job satisfaction includes questions about salary, work-life balance, and career growth opportunities 4. c) External validity 5. a) A researcher develops a new intelligence test and compares the scores with those obtained from an established intelligence test 6. c) The extent to which a research instrument consistently produces the same results 7. a) Test-retest reliability 8. c) Parallel forms reliability 9. a) Two researchers independently code and rate the same set of video recordings for aggression levels, and their ratings show a high level of agreement 10. b) Inter-rater reliability Topic-Validity and Reliability in Research Instruments 1. What is the primary purpose of assessing validity and reliability in research instruments? a) To ensure that the instrument measures what it intends to measure accurately and consistently b) To determine the popularity of the research instrument among participants c) To evaluate the cost-effectiveness of the research instrument d) To assess the ethical implications of using the research instrument 2. Which of the following best defines validity in the context of research instruments? a) The extent to which a research instrument consistently produces the same results b) The degree to which a research instrument measures what it is intended to measure c) The ability of a research instrument to be easily understood by participants d) The extent to which a research instrument is free from bias 3. Which of the following is an example of content validity? a) A survey designed to measure job satisfaction includes questions about salary, work-life balance, and career growth opportunities b) A researcher uses a ruler to measure the height of participants accurately c) A questionnaire is translated into multiple languages to ensure cultural validity d) A researcher conducts a study with a large sample size to increase external validity 4. Which type of validity refers to the extent to which the results obtained from a research instrument can be generalized to a larger population? a) Content validity b) Construct validity c) External validity d) Internal validity 5. Which of the following is an example of criterion-related validity? a) A researcher develops a new intelligence test and compares the scores with those obtained from an established intelligence test b) A survey is administered to a group of participants, and the same survey is re-administered to the same group after a month c) A research instrument consistently produces similar results when used by different researchers d) A researcher conducts a study in a controlled laboratory setting to ensure internal validity 6.
