Resampling

Resampling is a statistical technique used to evaluate a dataset by repeatedly drawing samples from it, often with replacement. This method helps to assess the reliability of statistical estimates or to improve predictions. For example, if you want to understand the average height of a group, you might repeatedly take samples of people's heights and calculate averages from these samples. This process provides insights into how much variation exists and helps to construct confidence intervals, leading to more informed conclusions about the overall population based on the data you have.
