The intent of our study was to extend TAM by
adding a playfulness concept in the WWW context.
We hoped to explain user acceptance of the WWW.
The hypothesized relationships were tested using
regression analysis to maintain consistency with earlier
studies. Table 5 presents a summary of the hypothesis
tests. In such research, a stepwise multiple
regression analysis technique is recommended examining
the contribution of each predictor variables to
the regression model [20]. More detailed results of the
stepwise regression results are shown in Table 6. Also,
a standard multiple regression analysis was conducted
to compare the model's overall predictive ®t (adjusted
R2) of the original TAM to that of the extended TAM.
Table 7 shows results of this comparison
