| PART – B : STATISTICS FOR ECONOMICS |
Choose the Correct Option:
1. What is the primary objective of data analysis?
(i) To increase the size of data.
(ii) To eliminate all data points.
(iii) To reduce the size of the original data to a single number.
(iv) To randomly organize the data.
Ans: (iii) To reduce the size of the original data to a single number.
2. Which of the following is not mentioned as a statistical tool for data analysis?
(i) Measures of dispersion.
(ii) Probability theory.
(iii) Correlation.
(iv) Index number.
Ans: (ii) Probability theory.
3. What is the primary objective of statistical analysis in the context of central tendency?
(i) To calculate all individual values in a dataset.
(ii) To determine a single value representing the entire dataset.
(iii) To identify the highest and lowest values in the dataset.
(iv) To find errors in the dataset.
Ans: (ii) To determine a single value representing the entire dataset.
4. Which of the following best defines the term ‘central tendency’?
(i) A value that is larger than all other values in a dataset.
(ii) A single figure that represents the whole dataset.
(iii) The difference between the highest and lowest values in a dataset.
(iv) A mathematical formula used to arrange data.
Ans: (ii) A single figure that represents the whole dataset.
5. In the example of comparing students’ marks between two schools, why is an average used?
(i) To calculate the total number of students in each school.
(ii) To compare the performance of students in a simple way.
(iii) To find the lowest marks obtained by students.
(iv) To determine the most intelligent student.
Ans: (ii) To compare the performance of students in a simple way.
6. Why is an average also called a ‘measure of location’ or ‘summary number’?
(i) Because it is always the smallest number in the dataset.
(ii) Because it represents a typical value around which other figures lie.
(iii) Because it is used only in economics and business studies.
(iv) Because it always equals the highest value in the dataset.
Ans: (ii) Because it represents a typical value around which other figures lie.
7. What is the primary function of an average in data analysis?
(i) To increase the complexity of data.
(ii) To organize data randomly.
(iii) To represent complex data in a simple and condensed form.
(iv) To replace all individual data points with new values.
Ans: (iii) To represent complex data in a simple and condensed form.
8. How do measures of central tendency help in comparison?
(i) By eliminating the need for calculations.
(ii) By reducing a large set of data into a single figure.
(iii) By increasing the number of observations in a dataset.
(iv) By avoiding numerical representations.
Ans: (ii) By reducing a large set of data into a single figure.
9. Why is the average wage income of workers useful?
(i) Because it hides individual variations.
(ii) Because it helps remember the wage incomes of all workers.
(iii) Because it provides a general understanding of income levels.
(iv) Because it replaces actual wage data.
Ans: (iii) Because it provides a general understanding of income levels.
10. In what way are averages important for economic analysis?
(i) They help in understanding individual income variations.
(ii) They assist in analyzing sectoral productivity differences.
(iii) They eliminate the need for data collection.
(iv) They increase the complexity of economic studies.
Ans: (ii) They assist in analyzing sectoral productivity differences.
11. Which of the following is an essential characteristic of an ideal average?
(i) Difficult to understand.
(ii) Rigidly defined.
(iii) Based on partial observations.
(iv) Easily affected by extreme values.
Ans: (ii) Rigidly defined.
12. Why should an ideal average be rigidly defined?
(i) To allow different methods of calculation to produce different results.
(ii) To ensure a definite and fixed value regardless of calculation method.
(iii) To make calculations more complex.
(iv) To ignore some observations.
Ans: (ii) To ensure a definite and fixed value regardless of calculation method.
13. An ideal average must be based on:
(i) The first and last observations only.
(ii) A selected sample of observations.
(iii) All observations in the dataset.
(iv) Only the largest and smallest values.
Ans: (iii) All observations in the dataset.
14. What is meant by an ideal average being capable of algebraic treatment?
(i) The sum of all values should be greater than the average.
(ii) The sum of values in a series should equal the product of the average and the number of observations.
(iii) It should be difficult to apply in algebraic calculations.
(iv) It should only be used for small datasets.
Ans: (ii) The sum of values in a series should equal the product of the average and the number of observations.
15. Which of the following statements about extreme values is true regarding an ideal average?
(i) It should be unduly affected by extreme values.
(ii) It should completely ignore extreme values.
(iii) It should not be unduly influenced by extreme values.
(iv) It should consider only extreme values for calculation.
Ans: (iii) It should not be unduly influenced by extreme values.
