I. Determine whether the following statements are true or false.

1. The group surveyed when the survey is not administered to all members of the

population is called a sample.

2. Sampling can be done when it would be impractical to survey the entire

population.

3. The choice of sampling technique is dependent on the research questions and

objectives and the achievability of gaining access to the data

4. Simple random sampling involves creating subgroups of the entire population,

usually based on the geographic location.

5. Cluster sampling is uses strata in determining samples.

9. How is stratified sampling carried out?

a. Divide the population into homogenous groups and proportionally select

random sample from each group.

b. Systematically choose samples by getting, say, every 8

th entry in a list.

c. Divide the population into groups and select all members of a random

group as samples.

d. Assign numbers to each member of the population then randomly select

numbers10.Which is an advantage of using simple random sampling?

a. It eliminates risk of getting biased respondents.

b. It is easy to use and likely represents the population

c. It is the easiest to use if the target population is spread out in a large

geographical area.
