False
Defect clustering is a well-known principle in software quality assurance that states most defects are clustered in a small number of modules. This follows the Pareto principle (80/20 rule) where 20% of modules typically contain 80% of defects. This pattern helps testers focus their efforts on high-risk areas. The statement correctly describes this concept.
Defect clustering is a well-known software testing principle stating that a small number of modules typically contain most of the defects found in a system — often cited alongside the Pareto principle (roughly 80% of defects in 20% of modules). This observation guides testers to focus extra effort on historically defect-prone or complex modules. The statement as given accurately describes this principle, so True is correct.
