Reliability & Validity Quick Kit

Composite reliability, AVE and Cronbach's alpha — computed in your browser, interpreted against the cited thresholds reviewers actually check.

1 · Composite Reliability & AVE from loadings

Paste your standardised factor loadings for one construct, one per line (e.g. 0.78).

2 · Cronbach's alpha from raw data

Paste raw responses: one respondent per line, items separated by commas, tabs or spaces (same item count per line).

Thresholds and citations

Composite reliability of .70 or higher indicates acceptable internal consistency for established scales (Hair, Black, Babin, & Anderson, 2019). Average variance extracted of .50 or higher indicates adequate convergent validity; where AVE falls below .50 but CR exceeds .60, convergent validity may still be judged adequate (Fornell & Larcker, 1981). Cronbach's alpha of .70 is the conventional floor for research instruments, with .80+ preferred for applied decisions (Nunnally, 1978). All computation happens in your browser — no data leaves this page.

Full measurement-model assessment involves discriminant validity, model fit and invariance — that is what we do.
