Description of Sampling and Data Collection

Question 1

a process used in statistical analysis in which a predetermined number of observations taken in larger population.

Answer 1

Sampling/Sample

Question 2

a sampling technique in which sample from a larger population are chosen using a method based on the theory of probability.

Answer 2

Probability Sampling

Question 3

Members of the population are given a chance of being selected.

Answer 3

Probability Sampling

Question 4

Probability sampling also known as?

Answer 4

scientific sampling

Question 5

method of collecting data where every single member of a population is chosen randomly, a merely by chance and each individual has the exact same probability of being chosen to be a part of a sample.

Answer 5

Simple Random Sampling

Question 6

A method where the researchers divide the, entire population into sections or clusters that represent a population.

Answer 6

Cluster Sampling

Question 7

a method where members of a sample are chosen at regular intervals of a population.

Answer 7

Systematic Sampling

Question 8

It requires selection of a starting point for the sample and sample size, that can be repeated at regular intervals.

Answer 8

Systematic Sampling

Question 9

a method where the population can be divided into smaller groups, that don’t overlap but represent the entire population together, while sampling, these groups can be organized and then draw a sample from each group separately.

Answer 9

Stratified random sampling

Question 10

reliant on a researcher’s ability to select members at random.

Answer 10

Non-Probability Sampling

Question 11

Non- Probability also known as?

Answer 11

Also known as non-scientific sampling

Question 12

the most common sampling strategy. In this type of sampling participants are selected or sought based on pre-selected criteria based on the research question.

Answer 12

Purposeful/Purposive Sampling

Question 13

a sampling technique, where by participant quotas are preset prior to sampling.

Answer 13

Quota Sampling

Question 14

You choose members of the population that are convenient and available

Answer 14

Convenience Sampling

Question 15

convenience sampling also known as?

Answer 15

also known as accidental or incidental sampling.

Question 16

In this method, the participants refer the researcher to others who may be able to potentially contribute or participate in the study.

Answer 16

Snowball Sampling

Question 17

Snowball Sampling also known as?

Answer 17

also known as chain referral sampling.

Question 18

This sampling method is not a fixed or pre-defined selection process which makes it difficult for all elements of a population to have equal opportunities to be included in a sample.

Answer 18

Non-Probability Sampling
