I don’t understand this Statistics question and need help to study.
Frankfort-Nachmias and Leon-Guerrero (2018) noted that the precision of a confidence interval can be enhanced by increasing the sample size.
Write a 350-word response to the following:
- How does sample size affect the validity of a study?
- What factors determine the size of an ideal sample?
- How is the sample size calculated?
