Millisecond Forums

Hi All,
As a new user of Inquisit Web 4, I have read through the post from Dave about how to interpret IAT data (https://www.millisecond.com/forums/Topic3444.aspx)
The post says:  The final 'd' score for a given participant thus appears on the last row of data for that participant. Inquisit reports 3 d scores, which appear in the last 3 columns labeled "expressions.da", "expressions.db", and "expression.d".

I can see the three columns corresponding to the 'da', 'db', and 'd' scores but in the AgeIAT file I'm looking at there is no "final d score" provided in the bottom row.  The bottom row is just another row measuring one specific stimulus item from the IAT.  The AgeIAT is from the list of scripts that Dave suggests does compute d (i.e., it is not an outdated script as was suggested to another user experiencing the same issue as me).

Is anyone able to offer me some thoughts on this?  Do I have to take an average of the entire d column to know each participants d score?  That will be very time-consuming as I have approx 200 participants.  Apologies for the noob question.

Thanks,
Mike
