Types of Reliability and Validity The Values and Motives Questionnaire (VMQ) has two measures to assess reliability. Reliability does not ensure that the information in the test is valid even though it measures a variable consistently (What Makes a Good Test, n.). On the other hand, validity measures determine whether the tests are valid or accurate (What Makes a Good Test, n.). Validity is measured using two different methods: criterion and construct validity. Criterion validity compares scores and shows that the scores are similar for the tests (What Makes a Good Test, n.). Construct validity measures the extent of the consistency of the tests and determines whether any scores are identical. The Values and Motives Questionnaire defines homogeneity as internal consistency. When the psychometric soundness of a test, the reliability and validity of a test are determined (Values and Motives Questionnaire, n.). Reliability: Cronbach Alpha Coefficients Cronbach’s Alpha reliability for internal consistency was for both males and females. In the VMI scales, many exceed the 0 level, which shows that those measures are acceptable. Some things were low scores on the scale, which belonged to achievement (.53), infrequency (.52), moral (.68), and independence scale (.66) (Values and Motives Questionnaire, n.). When looking at all of the scores, anyone with a score higher than .82 or higher on the standard measurement error means there is a slight chance of error. Also, if the Alpha score is .83, the measurement is accurate. Sample Size and Nature of the Population According to the Values and Motives Questionnaire, 159 psychologists and MBA students were included in the questionnaire, which is required for the introductory course of this assessment. Fifty-nine psychology undergraduates completed this questionnaire to receive

They did not have enough diversity within their sample to have traits that would be found within the average population. More information on the level of education the psychology students have is important because that can make it general. Your Opinion of the VMQ The VMQ was reliable and valid when looking at the whole test. It did not have enough information on the population that it was sampling. They stated they used both females and males, which makes the test more reliable. However, using random selection and more specific demographics must be supplied to make tests more reliable. This test was done on students with a higher education that does not represent the general population. If they provided more information on race, culture, gender, education levels, and further demographic information, it would have been needed to increase the validity and reliability of the test. The validity of the test also provided a range of 0 to 0, which shows that the results of the VMQ are not comparable (Values and Motives Questionnaire, n.).
