Why do qualitative researchers need to be as concerned with sample size as quantitative researchers do? Qualitative researchers:

a. are reaching the objectives of their study in a similar way.
b. need subjects who are able and willing to share their knowledge, oftentimes in repeated and more in-depth interviews than subjects in quantitative studies.
c. need to gain a narrow focus rather than a broad perspective as their research purpose.
d. will be analyzing the data with statistical techniques that require certain numbers of subjects.

Answer to Question 1

ANS: B
Qualitative research oftentimes requires the subjects to share their knowledge of the topic being studied in an in-depth level in repeated interviews. Therefore the researcher needs to ensure that the sample size is adequate to provide the depth and rich data that are required.
Qualitative researchers approach the objectives in a different fashion or process than quantitative researchers.
Qualitative researchers need to gain an in-depth focus rather than a broad perspective as their research purpose.
Qualitative researchers do not analyze the data with statistical techniques that require certain numbers of subjects.

Answer to Question 2

ANS: D
Stratified random sampling and quota sampling differ in randomness; quota sampling does not allow for equal likelihood of entering the sample from the target population.
Convenience and accidental sampling describe similar types of sampling methods.
Network and snowball sampling describe similar types of sampling methods.
Purposive and selective sampling describes similar types of sampling methods.
