Mann-Kendall test

The Mann-Kendall test is a statistical method used to identify trends in time-series data, such as temperature changes over several years or river flow rates. Essentially, it checks whether a dataset shows a consistent increase or decrease over time, without being affected by the actual values themselves. This test is valuable for researchers in fields like environmental science, hydrology, and climate studies, as it helps determine if observed trends are statistically significant, thereby informing decisions and policies based on those trends.
