Without using references, discuss how sampling affects the validity of a study. Would that be internal or external validity? How would you judge a sampling error in a study?
It is often wise to ask for references to check out the response. Let's take a closer look.
RESPONSE:
1. Without using references, discuss how sampling affects the validity of a study. Would that be internal or external validity?
The effect of sampling on validity is an interesting relationship.
(1) First, internal validity is impacted by sample size in descriptive or cross-sectional studies. In such studies, you measure each variable only once, and your outcomes are relationships between the variables. The lower the validity, the more the relationships are degraded, so the bigger the sample size you need to characterize them. So, if you have a smaller sample, the internal validity of the study is challenged due to this degradation of relationships between variables.
In other words, if your sample size was too small, you might not find a relationship ...
