4.1.3  Holistic Rating 
 
The results of the ANOVA for the holistic rating show no significant 
difference between the groups (F(2, 272) = 1.148, p = .3188).  As can be seen 
from Table 12, the mean holistic rating for each group is similar.

4.1.4  Target-Like Use of Articles  
 
The ANOVA for the dependent variable target-like use of articles (TLU) 
shows a significant main effect for the factor Group (F(2, 272) = 31.306, p = 
.0001). To examine the source of the significant effect for the factor Group, post-
hoc comparisons of the means for each group were performed.  The results of 
the comparisons are illustrated in Table 13.  There is a significant difference 
between all groups at the p < .05 level of significance.  The table of means, Table 
14, shows a steady increase in TLU from Group 1 to Group 3.
