The number of defects in a particular software is given by which metric?

Options
- Defect removal rate
- Defect density
- Mean time to failure
- Coverage metrics

CORRECT ANSWER : Defect density

Discussion Board
Defect density

Answer: Defect density
Solution: Defect removal rate: It is Defect removal efficiency (DRE). It is used to calculate the number of defects are in resolved states.
Defect Density: It is used to calculate the overall defect found in particular software.
Mean time to failure: It is used to calculate the expected time period for system failure.
Coverage metrics: It is used to calculate the coverage of code, statement coverage , line coverage etc.
Therefore, the correct answer is defect density.
