Match List-I with List-II.
| List-I | List-II | ||
| (A) | A measurable characteristic of a population is called : | (I) | Degree of freedom |
| (B) | A collection of objects, events etc. is : | (II) | Population |
| (C) | A measurable characteristic of sample is called : | (III) | Parameter |
| (D) | The number of independent values which have freedom to vary in computing as statistic is called : | (IV) | Statistic |
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
(A) A measurable characteristic of a population is called :
This matches (III) Parameter, for example the population mean \(\mu\).
(B) A collection of objects, events etc. is :
This matches (II) Population: the whole collection under study.
(C) A measurable characteristic of sample is called :
This matches (IV) Statistic, for example the sample mean \(\overline{x}\).
(D) The number of independent values which have freedom to vary in computing as statistic is called :
This matches (I) Degree of freedom; for example, n values with a fixed mean leave n − 1 free to vary.
