Organisation of Data MCQ questions with answers
The first 3 of 30 questions. Unlock the series for the rest, each with a solution.
Q1. In a continuous frequency distribution the class $40-50$ has a frequency of $12$. If this class interval is split equally into $40-45$ and $45-50$ assuming the items are evenly spread, the frequency density (frequency per unit width) of the original class was:
एक सतत बारंबारता बंटन में वर्ग $40-50$ की बारंबारता $12$ है। यदि इस वर्ग-अंतराल को समान रूप से $40-45$ और $45-50$ में विभाजित किया जाए, यह मानते हुए कि मद समान रूप से फैले हुए हैं, तो मूल वर्ग का बारंबारता घनत्व (प्रति इकाई चौड़ाई बारंबारता) था:
- A. $6$
- B. $12$
- C. $2.4$
- D. $1.2$
Solution
Frequency density $=\frac{\text{class frequency}}{\text{class width}}=\frac{12}{10}=1.2$ items per unit.
बारंबारता घनत्व $=\frac{\text{वर्ग बारंबारता}}{\text{वर्ग चौड़ाई}}=\frac{12}{10}=1.2$ मद प्रति इकाई।
Q2. Three of the following are quantitative (variable-based) classifications, while one is different. Identify the 'odd one out':
निम्नलिखित में से तीन मात्रात्मक (चर-आधारित) वर्गीकरण हैं, जबकि एक भिन्न है। 'असंगत (odd one out)' की पहचान कीजिए:
- A. Classification by age / आयु के अनुसार वर्गीकरण
- B. Classification by religion / धर्म के अनुसार वर्गीकरण
- C. Classification by weight / भार के अनुसार वर्गीकरण
- D. Classification by monthly income / मासिक आय के अनुसार वर्गीकरण
Solution
Income, weight and age are quantitative variables that can be measured numerically, whereas religion is an attribute, so it is a qualitative classification.
आय, भार और आयु मात्रात्मक चर हैं जिन्हें संख्यात्मक रूप से मापा जा सकता है, जबकि धर्म एक गुण/लक्षण है, अतः यह एक गुणात्मक वर्गीकरण है।
Q3. Assertion (A): In the exclusive method, an item whose value is exactly equal to the upper limit of a class is included in the next higher class. Reason (R): In the exclusive method the upper limit of one class is the same as the lower limit of the following class. Choose the correct option:
अभिकथन (A): अपवर्जी विधि में, वह मद जिसका मान किसी वर्ग की उपरी सीमा के ठीक बराबर होता है, अगले उच्चतर वर्ग में सम्मिलित किया जाता है। कारण (R): अपवर्जी विधि में एक वर्ग की उपरी सीमा अगले वर्ग की निम्न सीमा के समान होती है। सही विकल्प चुनिए:
- A. Both A and R are true, and R is the correct explanation of A / A और R दोनों सत्य हैं, और R, A की सही व्याख्या है
- B. Both A and R are true, but R is not the correct explanation of A / A और R दोनों सत्य हैं, परंतु R, A की सही व्याख्या नहीं है
- C. A is false but R is true / A असत्य है परंतु R सत्य है
- D. A is true but R is false / A सत्य है परंतु R असत्य है
Solution
Both are true facts of the exclusive method, and because the limits overlap, the borderline item is placed in the next class, so R correctly explains A.
दोनों अपवर्जी विधि के सत्य तथ्य हैं, और चूँकि सीमाएँ अतिव्यापित (overlap) होती हैं, सीमा-रेखा वाला मद अगले वर्ग में रखा जाता है, अतः R, A की सही व्याख्या करता है।
