User: In which non probability sampling methods do reasercher select participants based on specific characteristics or expertise that are relevant to the study 
A judgemental sampling 
B convenience sampling 
C. Snowball sampling 
D. Simple random sampling
Assistant: The non-probability sampling method where researchers select participants based on specific characteristics or expertise that are relevant to the study is:

*A. Judgemental sampling*

This method involves the researcher using their judgment to select participants who they believe will provide the most relevant information for the study.
User: Im which non probability sampling methods are participants selected based on referrals from other participants often used in studies involving hidden or difficult to reach population 
A. Judgemental sampling 
B. Snowball sampling 
C. Quota sampling 
D. Simple random sampling
Assistant: The non-probability sampling method where participants are selected based on referrals from other participants, often used in studies involving hidden or difficult-to-reach populations, is:

*B. Snowball sampling*

This method relies on existing study subjects to recruit future subjects from among their acquaintances, creating a "snowball" effect.
User: Which of the following methods involves dividing a population into subgroup the. Selecting a specific number of participants from each subgroup based on their proportion ti the overall population 
 
A quota sampling 
B. Stratified sampling 
C. Convenience sampling 
D. Snowball sampling
Assistant: The method that involves dividing a population into subgroups and then selecting a specific number of participants from each subgroup based on their proportion to the overall population is:

*B. Stratified sampling*

This technique ensures that each subgroup is adequately represented in the sample, which can lead to more accurate and reliable results.
User: Which non probability sampling technique would most likely be used when a reasercher wants to gather the opinion of people who have had direct experience with specific issue such as survivor of a disaster 
A. Quota sampling 
B. Judgemental sampling 
C. Snowball sampling 
D. Convenience sampling
Assistant: The non-probability sampling technique that would most likely be used when a researcher wants to gather the opinions of people who have had direct experience with a specific issue, such as survivors of a disaster, is:

*B. Judgemental sampling*

This method allows the researcher to select participants based on their specific experiences and relevance to the study.
User: Which of the following types of validity refers to the extent to which q measurement tool accurately measure the concepts it is intended to measure 
A. External validity 
B. Construct validity 
C. Internal validity 
D. Content validity
Assistant: The type of validity that refers to the extent to which a measurement tool accurately measures the concepts it is intended to measure is:

*B. Construct validity*

Construct validity assesses whether a test or instrument truly measures the theoretical construct it claims to measure.
