Correct answer: B. Convergent validityअभिसारी वैधता (Convergent validity)
Explanation
When different methods measuring the same thing lead to the same results, the measures agree or 'converge' – this is convergent validity (the logic behind methodological triangulation). Inter-rater and test-retest refer to agreement between raters and over time, which are really forms of reliability.जब एक ही चीज़ को मापने वाली भिन्न विधियाँ समान परिणाम देती हैं, तो मापन आपस में 'अभिसरित' होते हैं – यह अभिसारी वैधता (Convergent validity) है (पद्धतिगत त्रिकोणीयन का आधार)। अंतर-निर्णायक और परीक्षण-पुनर्परीक्षण निर्णायकों के बीच तथा समय के साथ सहमति को दर्शाते हैं, जो वस्तुतः विश्वसनीयता के रूप हैं।More Research Aptitude questions
