Question

Quizplus · Accepted Answer

Statistical power analysis allows researchers to determine the necessary sample size to achieve a desired level of statistical power, or the ability to detect a true effect in the population. This method takes into account factors such as effect size, significance level, and variability in the data to produce a more accurate estimate of the sample size needed for a study. Generalization refers to the ability to apply findings from a sample to the larger population, while inferential statistics and sample statistics are tools used to analyze data and draw conclusions based on the sample.
