Assertion (A): Random sample is representative of the universe: Reason (R): Random sample has the units of the universe who are opinion leaders

1. Both (A) and (R) are true
2. Both (A) and and (R) are true but (R) is not the correct explanation
3. (A) is true, but (R) is false

The consistency of a result or of a measure at different points in time is known as:

1. Snow ball
2. Multistage
3. Simulation
4. Stability

Indentify the correct combination of probability sampling:

2. Random — Systematic — Multistage — Stratified
3. Random — Systematic — Stratified — Multistage
4. Systematic — Stratified — Random — Multistage-

The snowball sampling method is useful when the universe is small and

2. specific
3. general
4. concentrated

A chain of referrals to identify respondents for collection of data will result in the sampling method known as

4. Observational

Response Rates do not relate to

2. Surveys
3. Sampling
4. References

The source of a sample is called

3. Respondent profile
4. Sampling frame

External validity can be achieved through:

The accuracy of systematic sampling is dependant upon the adequacy of:
