  "id": "MLC-T-CHM-008994",
  "term": "Plackett-Burman design",
  "field": "Chemistry",
  "definition": "A two-level fractional factorial experimental design used for screening a large number of factors to identify the ones with the most influence on a response. These designs are efficient for studying N-1 factors in N runs, where N is a multiple of four. The analysis focuses on main effects, as higher-order interactions are confounded with them, making this design suitable for initial screening rather than detailed process characterization.",
