Question:
A Study of Negative Suggestion (Douglas, Grebert, Webb, 2014). This group were interested in the effects of negative suggestion on members of the public. They placed a sign with the words “do not look up” in a highly visible area at the northern end of the Goodwill Bridge, and recorded whether or not people looked at the sign, and if so, for how long they looked up. They also recorded other variables such as gender, age group, attire, activity and time of day (am/pm). Following are some descriptive statistics of their analysis, for only the 109 people who looked up. The variable LogTime is the logarithm to base 10 of the time they looked up for.
