Correct answer: A. Interval and ordinalअंतराल (Interval) और क्रमसूचक (Ordinal)
Explanation
Marks awarded on an answer book form an interval scale — the gaps between scores are equal but there is no true zero. Converting those scores into ranks (1st, 2nd, 3rd …) gives only order, which is an ordinal scale. Nominal scales merely label, and ratio scales need an absolute zero, so neither applies here. Hence the teacher uses interval and ordinal scales.उत्तर-पुस्तिका पर दिए गए अंक अंतराल (interval) मापनी बनाते हैं — अंकों के बीच का अंतर समान होता है किंतु वास्तविक शून्य नहीं होता। इन अंकों को क्रम (प्रथम, द्वितीय, तृतीय …) में बदलने पर केवल क्रम मिलता है, जो क्रमसूचक (ordinal) मापनी है। नामिक मापनी केवल नाम देती है और अनुपात मापनी के लिए निरपेक्ष शून्य चाहिए, अतः वे यहाँ लागू नहीं होतीं। अतः शिक्षक अंतराल और क्रमसूचक मापनियों का प्रयोग करता है।More Research Aptitude questions
