Double Latin Square

A Double Latin Square is a structured way to organize experiments or data to control for two sources of variability simultaneously. It involves arranging two sets of symbols or treatments in a square grid, such that each symbol appears exactly once in each row and column, and each pairing of symbols occurs only once. This systematic design helps researchers evaluate multiple factors at once while minimizing bias and confounding variables, ensuring the results are more reliable and balanced. It’s a useful tool for experiments needing precise control over two variables without increasing complexity excessively.
