Question: Imagine that a researcher is measuring the time it takes participants to identify whether a string of letters constitutes a word (e.g., duke) or a nonword (e.g., dake). She measures the response time of 40 participants. She finds that most participants took from ½ to 1 second to make their decision but that one participant took 3 minutes to make a decision.
a. Why would the participant who took 3 minutes be considered an outlier?
b. What kinds of things might the researcher look for in an outlier analysis of this situation?
