Final answer:
Cronbach's alpha is a popular statistical method used to assess internal consistency of a psychometric test or any constructed scale. The correct answer is option b.
Step-by-step explanation:
One of the more popular statistical procedures used to assess internal consistency is Cronbach's alpha. Cronbach's alpha is extensively used in the realm of psychology, education, and social sciences to evaluate the reliability of a psychometric test or any constructed scale.
It indicates the extent to which all parts of the test contribute equally to what is being measured. The coefficient measures this consistency by averaging out all possible split-half reliability estimates, which makes it highly valuable for ensuring that multiple-question surveys or tests are reliable as a whole.
Other answers, such as the Pearson correlation coefficient, are more directly concerned with measuring the degree of linear relationship between two variables. The Analysis of Variance (ANOVA) is a method that looks at variances within and between groups to assess statistical differences.
