Hi Behrouz,

> 2 Questions:
> 1. For adding Discrimination Factor to Statistics table should
> I represent the "%Upper Award", "%Lower Award", "Upper Records", "Lower
> Records" in four more columns after the Dis.F. Column like old
> CAPA program or I should bring only Dis F.?

Only Dis. F.

> 2. Is that fine to bring the 2 discrimination factor criteria 1) [Total
> Partial Credit awarded / Total No of Tries] and 2) [Total No of Yes's /
> Total No of triers] simultenously in the table OR it should be optional.

Both unless it takes a long time to compute.
