Differentiable between stratified and cluster random samplings. |
| Answer» In stratified sampling, the sampling is done on elements within each stratum. In stratified sampling, a random sample is drawn from each of the strata, whereas in cluster sampling only the selected clusters are sampled. A common motivation of cluster sampling is to reduce costs by increasing sampling efficiency. | |
| 3. |
What is the difference between a census survey and a sample servey? |
| Answer» The sampling is defined as the subset of the population selected to represent the entire group, in all its characteristics. The census is alternately known as a complete enumeration survey method. Census, is a very time-consuming method of survey, whereas, in the case of sampling, the survey does not take much time. | |
| 4. |
Distinguish between primary and elemenatary samplying units. |
| Answer» The elementary units or the group or cluster of such units may form the basis of sampling process in which case they are called as sampling units. A list containing all such sampling units is known as sampling frame. Thus sampling frame consists of a list of items from which the sample is to be drawn. | |
| 5. |
Explain briefly systematic random sampling. |
| Answer» Systematic sampling is a statistical method involving the selection of elements from an ordered sampling frame. The most common form of systematic sampling is an equiprobability method. In this approach, progression through the list is treated circularly, with a return to the top once the end of the list is passed. | |
| 6. |
What is the difference between universe and sample? |
| Answer» A subgroup of the members of population chosen for participation in the study is called sample. The population consists of each and every element of the entire group. Universe is the set all experimental units, from which a sample is to be drawn. | |
| 7. |
Define unrestricted random sample. Name the two basis on which such a sample can be selected. |
| Answer» Unrestricted Random Sampling. The method of unrestricted random sampling (METHOD=URS) selects units with equal probability and with replacement. ... The expected number of hits (selections) for each unit equals when sampling without stratification.The two basis on which such a sample can be selected are Draw of lot basis and random number tables. | |
| 8. |
Name the four divisions of the NSSO and their headquarters. |
| Answer» The NSSO has four divisions namely Survey Design and Research Division (SDRD), Field Operations Division (FOD), Data Processing Division (DPD) and Co-ordination & Publication Division (CPD). Headquarters- Co-ordination & Publication Division is located at New Delhi and is responsible for: coordinating the activities of all the Divisions of NSSO. | |
| 9. |
Explain purposive sampling. |
| Answer» A purposive sample is a non-probability sample that is selected based on characteristics of a population and the objective of the study. Purposive sampling is different from convenience sampling and is also known as judgmental, selective, or subjective sampling. | |
| 10. |
The part of universe selected for investigation is called:A. PopulationB. SampleC. Primary sampling unitD. Elementary sampling unit. |
|
Answer» Correct Answer - B B |
|
| 11. |
Define restricted random sampling. Name its types. |
| Answer» Restricted Random Sampling A method of sampling is described which is a compromise between systematic sampling and stratified random sampling.Its types are Stratified, Cluster and Systematic sampling. | |
| 12. |
What is sampling? Give meaning of random sampling. |
| Answer» Sampling is a process used in statistical analysis in which a predetermined number of observations are taken from a larger population. The methodology used to sample from a larger population depends on the type of analysis being performed but may include simple random sampling or systematic sampling.Random sampling is a procedure for sampling from a population in which (a) the selection of a sample unit is based on chance and (b) every element of the population has a known, non-zero probability of being selected. | |
| 13. |
Explain what the Census of India provides. |
| Answer» Population Census is the total process of collecting, compiling, analyzing or otherwise disseminating demographic, economic and social data pertaining, at a specific time, of all persons in a country or a well-defined part of a country. | |
| 14. |
Suppose size of the Universe is 1000. the size of sample is 100.A. 7B. 11C. 15D. 20 |
|
Answer» Correct Answer - A A |
|
| 15. |
Simple Random Sampling is:A. Stratified samplingB. Cluster samplingC. Systematic samplingD. Unrestristed sampling |
|
Answer» Correct Answer - D D |
|
| 16. |
Explain briefly cluster random sampling. |
| Answer» Cluster sampling is a sampling plan used when mutually homogeneous yet internally heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this sampling plan, the total population is divided into these groups and a simple random sample of the groups is selected. | |
| 17. |
Explain briefly the method of unrestricted (or simple) random sampling. |
| Answer» The method of unrestricted random sampling (METHOD=URS) selects units with equal probability and with replacement. Because units are selected with replacement, a unit can be selected for the sample more than once. The expected number of hits (selections) for each unit equals when sampling without stratification. | |
| 18. |
List the subjects covered under the NSSO surveys. |
