Hey there,

I would like to give the participants some feedback on their D measure at the end of the completed IAT. However, I do not really want to have the computed D measure with all decimals appearing on the screen, since this looks rather confusing but I only want to display the first two or three decimals. If I use the function <% round(expressions.d) %>, only the next integer is displayed, without any decimals.

Is there a way how I can display the first two or three decimals, e.g. "Your D measure equals 1.05" instead of "Your D measure equals 1" (when I use the round function), and omit the rest of the 7 or 8 decimals that are returned by default?

Thanks for ideas and comments!

Add a new entry to the <expressions> element

<expressions>
/ d2dec = format("%.2f", expressions.d)
[...]
</expressions>

and change <text summary> to refer to the new expression

<text summary>
/ items = ("Your IAT score (D) was <% expressions.d2dec %>, which suggests <% values.magnitude %> automatic preference for <% expressions.preferred %> compared to <% expressions.notpreferred %>.~n~n~nPress the spacebar to complete this session.")
[...]
