Q1. Identify the 'odd one out' from the following terms used in this chapter:
इस अध्याय में प्रयुक्त निम्नलिखित पदों में से 'असंगत (odd one out)' की पहचान कीजिए:
- A. Qualitative / गुणात्मक
- B. Geographical / भौगोलिक
- C. Exclusive / अपवर्जी
- D. Chronological / कालानुक्रमिक
Solution
Geographical, chronological and qualitative are all bases/types on which data is classified, whereas 'exclusive' is a method of forming continuous class intervals — so it is the odd one out.
भौगोलिक, कालानुक्रमिक और गुणात्मक सभी वे आधार/प्रकार हैं जिन पर आँकड़ों का वर्गीकरण किया जाता है, जबकि 'अपवर्जी' सतत वर्ग-अंतराल बनाने की एक विधि है — अतः यही असंगत है।
Q2. In the series $0-10$, $10-20$, $20-30$, the number of observations lying in the class $10-20$ is $8$. In the language of this chapter, the figure $8$ is called the:
श्रेणी $0-10$, $10-20$, $20-30$ में, वर्ग $10-20$ में आने वाले प्रेक्षणों की संख्या $8$ है। इस अध्याय की भाषा में, आँकड़े $8$ को कहा जाता है:
- A. Class limit / वर्ग सीमा
- B. Class mark / वर्ग चिह्न
- C. Class size / वर्ग आकार
- D. Class frequency / वर्ग बारंबारता
Solution
The number of observations falling in a particular class is called the class frequency (or frequency of that class). The class mark would be $15$ and the class size would be $10$.
किसी विशेष वर्ग में आने वाले प्रेक्षणों की संख्या को वर्ग बारंबारता (अथवा उस वर्ग की बारंबारता) कहा जाता है। वर्ग चिह्न $15$ होगा और वर्ग आकार $10$ होगा।
Q3. When raw data is grouped into a frequency distribution with classes, which of the following is a genuine limitation of the classified data?
जब कच्चे आँकड़ों को वर्गों वाले बारंबारता बंटन में समूहित किया जाता है, तो निम्नलिखित में से कौन-सी वर्गीकृत आँकड़ों की वास्तविक सीमा (limitation) है?
- A. The data can no longer be compared across groups / आँकड़ों की समूहों के बीच तुलना अब नहीं की जा सकती
- B. The total frequency becomes greater than the number of observations / कुल बारंबारता प्रेक्षणों की संख्या से अधिक हो जाती है
- C. The identity and exact value of individual observations are lost / व्यक्तिगत प्रेक्षणों की पहचान और सटीक मान खो जाते हैं
- D. The number of classes automatically becomes equal to the range / वर्गों की संख्या स्वतः परिसर के बराबर हो जाती है
Solution
Classification condenses the data but the exact value of each individual observation is lost; we only know how many items fall in each class, not what they were. This is the 'loss of information' caused by classification.
वर्गीकरण आँकड़ों को संघनित कर देता है परंतु प्रत्येक व्यक्तिगत प्रेक्षण का सटीक मान खो जाता है; हमें केवल यह ज्ञात होता है कि प्रत्येक वर्ग में कितनी मदें आती हैं, न कि वे क्या थीं। यह वर्गीकरण के कारण होने वाली 'सूचना की हानि' है।
