Levene’s test of homogeneity of variance with p=0.62, indicates the data is suitable for
ANOVA analysis (Table 7.7). The result from the One-Way ANOVA indicate that the
overall mean number of products purchased in a single transaction is less via cash than via a
debit card payment mode, F= 4.54, p=0.035. So Proposition 2b is supported.
Examination of proposition 2c: The overall mean amount spent on indulgence food
products purchased in a single transaction will be less via cash than via a debit card
payment mode.
Whilst what is termed ‘indulgence’ food products is determined by individual viewpoints,
for this study indulgence foods are categorised as those that, in most instances would be
deemed not necessary and within the categories identified in Exhibit 4.3- snack,
confectionary and desserts are classified as indulgence foods.
As the results in Table 7.8 shows users of debit cards spend more, but do not buy more
though the difference is statistically significant. So the support for Proposition 2c is
equivocal. One possible explanation could be smaller sample size could have restricted
statistical significance.
