Answer:
Criterion validity
Step-by-step explanation:
The results show that people who identified themselves as political conservatives also had the highest scores on his questionnaire .This is an indication of the criterion validity of the new instrument.
Criterion validity is used to measures and predicts an outcome for another measure, i.e the extent to which a measure is related to an outcome and it assesses whether a test reflects a certain set of abilities.For instant, during an interview job applicant takes a performance test during the interview process. If this test accurately predicts how well the employee will perform on the job, the test is said to have criterion validity.
Likewise, the researcher here designed a new questionnaire to measure political conservatism, where he asks people leaving their polling place on election day to report their degree of political conservatism on a scale of 1 to 10 (low-high) in order to measure their political views.
