Explanation
Scaling is the procedure of assigning numbers to various degrees of opinion, attitude and other abstract concepts so that qualitative responses can be handled quantitatively (e.g. Likert, Thurstone, Guttman scales). Regression predicts one variable from another, variance measures dispersion, and concordance measures agreement among rankings.स्केलिंग (मापनी-निर्माण) वह प्रक्रिया है जिसमें विचार, अभिवृत्ति तथा अन्य अमूर्त अवधारणाओं की विभिन्न कोटियों को संख्याएँ प्रदान की जाती हैं, ताकि गुणात्मक अनुक्रियाओं का मात्रात्मक विश्लेषण किया जा सके (जैसे लिकर्ट, थर्स्टन, गटमैन मापनियाँ)। समाश्रयण एक चर से दूसरे का पूर्वानुमान करता है, प्रसरण अपकिरण मापता है तथा सहमति-गुणांक क्रमांकनों के बीच सहमति मापता है।More Research Aptitude questions
