Sample size
1 answer
Sample size refers to the number of individuals or units that are included in a research study or experiment. It is the number of participants or observations that are gathered and analyzed to draw inferences and conclusions about a larger population. A larger sample size generally leads to more accurate and reliable results, but it can also increase the cost, time, and effort required to conduct the study. The appropriate sample size depends on the research question, study design, statistical power, and level of precision desired.
