Reliability and Validity Discussion Board

The website I found helps users calculate composite reliability online by entering pertinent information in the provided calculation space. The website, whose link is provided below, offers little information about reliability but provides several formulas that can be applied manually to calculate reliability when a user has come data ready.

To calculate composite reliability, a user is expected to feed information such as sample size, error variance, and R-Square. Since some statistical values do not naturally exist have to be calculated, as a user might have to do some calculations before getting the correct deal to insert in the website reliability calculation.

I found it complicated to run tests with answers beyond the Likert scale and the dichotomous variables. For example, for a Likert scale, it is evident that I would enter data in Microsoft Excel ranging from 1-5 where 1= strongly disagree, 2= disagree, 3= Neural/Undecided, 4= agree, and five represented strongly agree. Making up with the type of data becomes straightforward. I would think of a situation that requires the application of a Likert scale; through hypothetical data,...
