Hi there, I am a student conducting an experiment about the McGurk Effect
(where when a word is seen spoken while a different word is heard through
headphones, the perceived word is an integration of the two). I am hoping
to cue either the auditory word or the visual word before presenting the
video and sound to see if that makes the word more detectable.
My problem is that I will have to ask participants to select which word they
hear from a choice of 3 - the auditory word, the visual word, and the McGurk
integration. This therefore constitutes nominal data. The only statistical
test I can find to use on nominal data is a chi square, is this right? My
textbook says that I can only use a chi square if each participant only
contributes one piece of data, and only participates in one condition, which
is unrealistic in a study like this, so can I use chi sqaure, and if not,
what should I use?
Hope someone can help me,
thanks,
Kathryn
