Q1. Which of the following statements about the exclusive method of classification is/are correct? (i) The upper class limit of one class is the lower class limit of the next class. (ii) An item equal to the upper limit is counted in the next higher class. (iii) There is a gap between the upper limit of one class and the lower limit of the next.
वर्गीकरण की अपवर्जी विधि के बारे में निम्नलिखित में से कौन-सा/से कथन सही है/हैं? (i) एक वर्ग की ऊपरी वर्ग सीमा अगले वर्ग की निचली वर्ग सीमा होती है। (ii) ऊपरी सीमा के बराबर मद को अगले उच्चतर वर्ग में गिना जाता है। (iii) एक वर्ग की ऊपरी सीमा और अगले वर्ग की निचली सीमा के बीच एक अंतराल होता है।
- A. (i), (ii) and (iii) / (i), (ii) और (iii)
- B. (i) and (ii) only / केवल (i) और (ii)
- C. (i) and (iii) only / केवल (i) और (iii)
- D. (ii) and (iii) only / केवल (ii) और (iii)
Solution
In the exclusive method limits overlap (i) and the value equal to the upper limit goes to the next class (ii); the gap in (iii) belongs to the inclusive method.
अपवर्जी विधि में सीमाएँ अतिव्यापी होती हैं (i) तथा ऊपरी सीमा के बराबर मान अगले वर्ग में जाता है (ii); (iii) में दिया गया अंतराल समावेशी विधि से संबंधित है।
Q2. A table in which a discrete variable is shown with each of its distinct values against their frequencies, without forming class intervals, is called a:
एक ऐसी सारणी जिसमें किसी असतत चर को वर्ग अंतराल बनाए बिना, उसके प्रत्येक भिन्न मान को उनकी बारंबारताओं के सामने दर्शाया जाता है, कहलाती है:
- A. Inclusive series / समावेशी श्रेणी
- B. Bivariate frequency distribution / द्विचर बारंबारता बंटन
- C. Continuous frequency distribution / सतत बारंबारता बंटन
- D. Frequency array / बारंबारता सारणी (frequency array)
Solution
A frequency array lists each separate value of a discrete variable with its frequency, so no class intervals are formed.
बारंबारता सारणी (frequency array) में किसी असतत चर के प्रत्येक पृथक मान को उसकी बारंबारता के साथ सूचीबद्ध किया जाता है, अतः कोई वर्ग अंतराल नहीं बनाया जाता।
Q3. Assertion (A): When raw data are grouped into a frequency distribution, some information about individual observations is lost. Reason (R): In a class interval the exact value of each item is replaced by the class, not the actual figure. Choose the correct option:
अभिकथन (A): जब कच्चे आँकड़ों को बारंबारता बंटन में वर्गीकृत किया जाता है, तो व्यक्तिगत प्रेक्षणों के बारे में कुछ जानकारी नष्ट हो जाती है। कारण (R): एक वर्ग अंतराल में प्रत्येक मद का वास्तविक मान वर्ग द्वारा प्रतिस्थापित कर दिया जाता है, न कि वास्तविक आँकड़े द्वारा। सही विकल्प चुनिए:
- A. A is false but R is true / A असत्य है परन्तु R सत्य है
- B. Both A and R are true and R is the correct explanation of A / A और R दोनों सत्य हैं तथा R, A की सही व्याख्या है
- C. A is true but R is false / A सत्य है परन्तु R असत्य है
- D. Both A and R are true but R is not the correct explanation of A / A और R दोनों सत्य हैं परन्तु R, A की सही व्याख्या नहीं है
Solution
Grouping keeps only the class, not each individual value, so detail is lost; thus R correctly explains A.
वर्गीकरण में केवल वर्ग रखा जाता है, प्रत्येक व्यक्तिगत मान नहीं, इसलिए विवरण नष्ट हो जाता है; अतः R, A की सही व्याख्या करता है।
