Practical Research (2ND SEM - Part II) Last Examination

Question 1

4 types of Probability Sampling

Answer 1

Simple Random Sampling
Stratified Random Sampling
Cluster Sampling
Systematic Sampling

Question 2

6 types of Non- Probability Sampling

Answer 2

Accidental or Convenience Sampling
Modal Instance Sampling
Expert Sampling
Proportional or Non - Proportional Quota Sampling
Heterogeneity or Diversity Sampling
Snowball Sampling

Question 3

4 Calculating sample size for a simple random sampling

Answer 3

Population Size
Margin error
Confidence Level
Standard deviation

Question 4

2 Technical Qualities of Research Instruments

Answer 4

Validity
Reliability

Question 5

Way of choosing individuals in which all members of the accessible population are given an equal chance to be selected.

Answer 5

Simple Random Sampling

Question 6

The samples are chosen from these subgroups and not directly from the entire population.

Answer 6

Stratified Random Sampling

Question 7

This procedure is usually applied in large-scale studies,
geographical spread out of the population is a challenge, and gathering information will be very time-consuming

Answer 7

Cluster Sampling

Question 8

This procedure is as simple as selecting samples every nth (example every 2nd, 5th) of the chosen population until arriving at a desired total number of sample size. Therefore, the selection is based on a predetermined interval

Answer 8

Systematic Sampling

Question 9

Participants are sampled according to what is conveniently available

Answer 9

Accidental or Convenience Sampling

Question 10

Participants who exhibit the “most common” occurrence are sampled accordingly

Answer 10

Modal Instance Sampling

Question 11

Participants who are identified as “experts” or those participants that can give a high-quality information are sampled

Answer 11

Expert Sampling

Question 12

A predetermined number or percentage of the population is sampled

Answer 12

Proportional and Non- Proportional Quota Sampling

Question 13

Samples who exhibit a wide spectrum of the identified characteristic are sampled.

Answer 13

Heterogeneity or diversity sampling

Question 14

Participants identify other potential participants to be included as samples

Answer 14

Snowball Sampling

Question 15

5 Steps in Selecting a Research Instrument

Answer 15

Identify a dependent variable
Conceptually define the variable
Identify nuances and particulars of the variables
Operationally define the variable
Select an appropriate instrument
