Exploring Reliability and Validity
Exploring Reliability and Validity Types of reliability and validity used in the ââ¬Å"Values and Motives Manualâ⬠One type of testing reliability used in the article is the inters of valid scores shown by the correlation co-efficient between VMI affection and 16PF are ââ¬Ëprivatenessââ¬â¢ with a coefficient of -0.41, social desirability/ impression management with a correlation coefficient of 0.4, and those with higher values (Values and Motives Questionnaire, n.d., p. 23, table 5). VMI and OPP constructs indicate two scores having a correlation coefficient of 0.7. It indicates that the scores are strongly related. As a result of strong correlation, the social desirable coefficient for the two constructs is 0.58, and a central responding correlate of 0.75. Correlation coefficients that are less than 0.5 (normal) are invalid. For VIM/OPP, the valid scores are altruism/ cynical-trusting (0.51), traditional/ detailed-flexible (-0.58), affiliation/ reserved-gregarious (0.73) among others (Values and Motives Q uestionnaire, n.d., p. 25, table 6). Sample size and nature of population The larger the sample size, the lower the standard error. A high value in the standard error reduces the validity of the test. It may indicate that the scores are different from those in the population. The samples have been selected from a population which tends to have a higher education index than the overall population in the country. The population is more sophisticated because it mainly consists of undergraduate and postgraduate students. The research outcome may be different if the sample if drawn from the countryââ¬â¢s population (Values and Motives Questionnaire, n.d.). An opinion about the test The test is valid and reliable if it used to interpret values among college students. It includes both undergraduate and postgraduate students. However, it cannot be used to make conclusions about the countryââ¬â¢s population.Advertising We will write a custom critical writing sample on Exploring Reliability and Validity specifically for you for only $16.05 $11/page Learn More Kaplan, R., Saccuzzo, P.
