Demonstrates an ABRUPT CHANGE from the established average value for 3 days in a row.

An abrupt change from the established average that persists for several days indicates a shift in the process mean. In QC terms, the central tendency has moved to a new level, not just a temporary fluctuation. A trend would be a gradual increase or decrease over time, not a sudden jump to a new mean. Dispersion refers to a change in how spread out the data are around the mean, not to the mean itself. So seeing three consecutive days with values consistently above or below the previous average is best described as a shift in the process.
