Variance Reduction

Variance reduction is a technique used to improve the accuracy of predictions or estimates by minimizing variability in the results. In statistics or data analysis, it involves methods to reduce the spread in a set of data, leading to more reliable conclusions. For instance, when conducting experiments or simulations, variance reduction techniques can involve using repeated measurements, combining information from multiple sources, or adjusting the way samples are selected. The goal is to increase the precision of the outcomes, making it easier to identify true patterns or effects while reducing the influence of random fluctuations.
