7.4.1.2: Control Group-Test Groups Comparison
(1) Cash users: Control and Test Group
The comparison with the cash group shows cash users spend $49 less than debit card users.
To gain further insights, the credit card users were isolated from the control group and the
‘owned money’ group were compared against the cash and debit card.
The only significant difference observed is between the control group (owned money) and the
debit card test group (F=4.30, p=0.04). To determine if this was due to the influence of the
cash users in the control group, the cash and debit users in the ‘owned money’ category were
separated. Cash users in the control group spent an average of $75, whereas debit card users
spent $130 and credit users $167. The sample size is however too small to make a definitive
conclusion, but there is an indication that cash users do spend less; that debit card and credit
card users spend more, with credit card users spending more than debit card users.
