👉 Runs math, also known as the Runs Calculation or Runs Test, is a statistical method used to assess whether a sequence of data points contains a significant number of consecutive increases or decreases. This test is particularly useful in non-parametric analysis, where it helps determine if the data exhibits a trend over time or if the observations are randomly distributed. The process involves counting the number of consecutive runs in ascending order (runs of increases) and descending order (runs of decreases). A significant number of runs in one direction suggests a trend, while symmetry around zero indicates no trend. The test is often applied in fields like economics, finance, and environmental studies to analyze time series data for underlying patterns or shifts.
