q2 · i? · quant-synthesis · r2

Narrative synthesis of reliability data from the 24 included studies. The review reports alpha values of 0.80 and 0.75 for structured viva and notes reliability coefficients of "(0.7 to 0.8) for the use of a structured rating procedure for viva compared to 0.3 to 0.4 for an unstructured viva exam". No standardized effect size is printed.

"Cronbach alpha of structured viva was α = 0.80 compared to α = 0.50 to the conventional viva as described by Madhukumar et al. [1], it was α = 0.75 as described by Anastaki et al. (27)"

Discussion¶

Related Claims¶

• Structured oral examinations show higher reliability than traditional formats, with median Cronbach's alpha of 0.75 across studies — a broader claim this one bears on
• Structured viva shows positive significant correlations with standard assessment tools (MCQs, OSCE, structured theory exam) while traditional viva does not correlate significantly with the structured theory exam — related
