DATA COLLECTION

Question 1

» gives precise and consistent information

» impractical with large samples

Answer 1

DIRECT METHOD / FACE TO FACE INTERVIEW

Question 2

» saves time in processing the data, as well as
saving the interviewer from carrying around
hundreds of questionnaires

» can be expensive to set up and requires that
interviewers have computer and typing skill

Answer 2

DIRECT METHOD / COMPUTER ASSISTED PERSONAL INTERVIEWING

Question 2

» less time consuming and less expensive

» response rate is not as high as face–to–face interview

Answer 2

DIRECT METHOD / TELEPHONE INTERVIEW

Question 2

» This type of research is often quicker and less
detailed.

» Some disadvantages of this method include
the exclusion of people who do not have a
computer or are unable to access a computer.
Also the validity of such surveys are in question
as people might be in a hurry to complete it and
so might not give accurate responses.

Answer 2

INDIRECT METHOD / WEB BASED QUESTIONAIRES

Question 3

» People are more truthful while responding to
the questionnaires regarding controversial
issues in particular due to the fact that their
responses are anonymous

» Majority of the people who receive
questionnaires don’t return them and those who
do might not be representative of the originally
selected sample

Answer 3

INDIRECT METHOD / PAPER-PENCIL QUESTIONAIRES

3.) It is the listing of all individual units in the
population or in the sample.

Answer 10

1.) TARGET POPULATION

2.) SAMPLED POPULATION

3.) THE FRAME

Question 11

1.) Any method of sampling that utilizes some form of random selection. Performed a group (sample) by selecting for study from a larger of subjects group

Answer 11

PROBABILITY SAMPLING

Question 12

most common techniques for selecting simple
random samples are by using strips of paper, use
of printed table of random numbers, or use of
random numbers generated by many computer
programs or scientific calculators.

Answer 12

Simple Random Sampling

Question 13

this sampling method involves dividing the population into homogenous subgroups and then taking a simple random sample in each subgroup

Answer 13

Stratified Random Sampling

Question 14

method of selecting a sample by taking every kth
element from an ordered population, the first
being selected at random

Answer 14

Systematic Random Sampling

Question 15

this sampling method involves dividing the
population into clusters, usually along geographic
boundaries, then randomly taking samples of
clusters, and measuring all units within sampled
clusters.

Answer 15

Cluster Random Sampling

Question 16

a complex form of cluster
sampling in which two or more levels of units are
embedded one in the other. The first stage consists
sample from. In the second stage, a sample
of constructing the clusters that will be used to
of primary units is randomly selected from each cluster
(rather than using all units contained in all selected
clusters).

used frequently when a
complete list of all members of the population does
not exist and is inappropriate

Answer 16

Multistage sampling

Question 17

most common method of sampling,
primarily based on the convenience
which is of the researcher

Answer 17

Accidental, Haphazard or Convenience Sampling

Question 18

samples are taken with a purpose in mind

Answer 18

Purposive Sampling

Question 19

commonly used in informal public opinion polls

Answer 19

Modal Instance Sampling

Question 19

Respondents are selected non-randomly
according to some fixed quota.

Answer 19

Quota Sampling

Question 19

the major characteristics of the population
are represented by sampling proportional
amount of each.

Answer 19

Proportional quota sampling

Question 20

the minimum number of sampled units
preferred in each category is specified

Answer 20

Non - proportional quota sampling

Question 21

performed when all opinions or views about a specific topic are primarily concern and representing these views proportionately is not of major importance.

Answer 21

Heterogeneity Sampling (sampling for diversit

Question 22

useful when populations that are inaccessible or hard to find are the target population.

Answer 22

Snowball Sampling
