Research Method 1

Convenience sampling is a type of

• probability sampling which involves the sample being drawn from that part of the population which is close to hand.

• non-probability sampling which involves the sample being drawn from that part of the population which is close to hand.

• probability sampling which involves the sample being drawn randomly from the subgroups.

Systematic sampling can be obtained by

• systematically selecting two element from the first k element in the frame and every 7-th element there after is called seven-in-k.

• heterogenously selecting one element from the first k element in the frame and every k-th element there after is called h-in-k.

• randomly selecting one element from the first k element in the frame and every k-th element there after is called one-in-k.

Probability sampling is a

• type of sampling where each element in the population has a zero probability of being selected

• type of sampling where each element in the population has a non-zero probability of being selected

• type of sampling where each element in the population has a probability of being selected

The following is true about simple random sampling EXCEPT

• the sample can be drawn using random table/generator

• every element in population has a known and equal chance of being selected as a subject

• it is also known as accidental sampling

Cluster sampling can be categorized into the followings EXCEPT for

• triple-stage sampling

• single-stage sampling

• area sampling

Double sampling is a sampling method which make use of

• secondary data

• digital data

• ouxiliary data

Multiphase sampling is a process that include

• collecting data from a sample using a previous technique

• collecting data from a sample using two different technique

• collecting data from a sample of a previous study of similar nature

The following is TRUE about snowball sampling except for

• Initial sample group can be selected by probability or non-probability method

• New subjects are selected based on recommendation by the initial subjects

• This method is used to locate members of common populations

Which of the following represents non-probability sampling?

• Stratified random

• Cluster

• Quota

A researcher gives instructions to each interviewer to select a sample consisting if 90 people under the age of 30 and 60 people over the age of 30 because that is the proportion of people with that characteristic in the population. This example of a _________ sample.

• Judgement

• Quota

• Proportional stratified
