Answer / amrita

One of the above examples is right..

EX : 30 bugs found for 1200 lines code
Defect Density: 30 / 1200
Defect Density: 0.025

This is only Defect Density.

Weighted Defect density is you multiply the no. of defects
with a number. like for High critical defects - 5 ; medium
critical defects - 3 ; and for low critical defects - 1 ;

Weighted defects are say for example among the 30 defects
received 10 are High critical; 15 are Medium critical and 5
are low critical. Then
10X5=50
15X3=45
5X1=5
total: 50+45+5=100

Weighted defects density is: 100/1200 = 0.0833.

Answer / chitra

Review defect can be measured by defect density where we
capture only number of defects identified, but does not
capture how well the reviewer finds the defects.
Review efficiency would be measured by the combination of
the number of defect and the weighted defect type.

example weighted defect:
To find the spell defects its easy to find it.It can be
weighted at 1.
But to find the architectural defect it requires efficiency
that can be weighted 4.

This example shows how we can see the efficiency not only
by number of defect but also by the nature(tough to
identify) of the defect.

Answer / karunakar reddy

defect density means
no of defects found in an application/kloc
kloc means 1000m lines of code
if it is worng,plz be mailing me

Number of lines of piece of code in above comment

Answer / sai charan

Defect Density : The number of Valid Bugs are reported /
Number of Piece of Code

EX : 30 bugs found for 1200 lines code

Defect Density : 30 / 1200

Defect Density : 0.025

Weighted defect and Defect density both are same.
