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.") [...] </text>
thank you so much, it works perfectly.
Have a nice day,
