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.
