Discover how to determine the ideal percentage of a population for a representative sample to ensure accurate data analysis with minimal sampling error.

The concept of effective population size (N e) provides a way to quantify the evolutionary changes caused by random processes in finite populations (Charlesworth, 2009). Since its formal definition by ...

Back in the day, we learned in statistics that you need a sample size of at least 2% of the size of population to make statistically significant conclusions about the behavior of the population. In ...

Power analyses and sample size calculations are important parts of many research projects. Often, before data are even collected, it is necessary to calculate and justify the required sample size for ...
