For example, the mean salary of all adults in a country. But collecting data of the entire population is almost always infeasible. Therefore, we use samples of the population to get a point estimate of our parameter of interest. But, what is the 95% confidence interval of your … Continue reading Bootstrapping – A Powerful Resampling Method in Statistics
