Resolution of a design

  "id": "MLC-T-CHM-010236",
  "term": "Resolution of a design",
  "field": "Chemistry",
  "definition": "A characteristic of a fractional-factorial experimental design that describes the degree to which main effects and low-order interactions are confounded or aliased with each other. A higher resolution design means that fewer main effects and low-order interactions are aliased with other main effects or low-order interactions. For example, a Resolution III design aliases main effects with two-factor interactions.",
