Question One: Another researcher considered the Data Output One and suggested that this did not really tell us much about peoples' intentions to binge drink in the future. They argued that these were cognitive suppositions recorded as a one-off measure (attitude) towards a 11 hypothetical consideration of future drinking (intention). They thus argued that a better determinant of intention to binge drink in the future would be whether people had previously engaged in binge drinking. They therefore split the group of participants into two levels (those who had previously engaged in binge drinking [n=36] and those who hadn't [n=50]) and considered whether there would be a significant difference in their intentions to binge drink in the future. The output is reported as a one-tailed analysis. Two participants' data for the intention to drink scale are not reported as they did not complete the report of whether they had previously engaged in binge drinking. Please download Data Output Two from the assignment brief module page to view the output so you can write up the analysis. Hypothesis: People who have previously engaged in binge drinking are more likely to intend to binge drink in the future, than those who have not previously engaged
