Data quality
Two items, “In your opinion, how accurate was the data gathered during the
vocabulary test?” and “I felt that others took the vocabulary test seriously.” embedded in
the eight questions about the two tasks required participants to rate the vocabulary test
data quality. A 2 x 2 ANOVA with data accuracy on the vocabulary test as the dependent
variable revealed that participants rated the data accuracy as reliably lower with an
outgroup authority (M=3.81) in comparison to an ingroup authority (M=4.66):
F(1,52)=6.82, p<.05, 2=.12. As shown in Figure 1, this pattern is qualified by a
statistically significant interaction between authority and cheater group affiliation:
F(1,54)=5.97, p<.05, 2=.10.
Simple effects analyses showed that for an ingroup cheater, participants rated the
data quality as more accurate for an ingroup authority (M=4.90) in comparison to an
outgroup authority (M=3.27): F(1,54=12.67, p<.001. For an outgroup authority,
participants rated the data quality as less accurate for an ingroup cheater (M=3.27) in
comparison to an outgroup cheater (M=4.36): F(1,54)=5.79, p<.05. For an ingroup
authority, participants did not rate the data quality as reliably less accurate for an ingroup
cheater (M=4.90) in comparison to an outgroup cheater (M=4.41): F(1,54)=0.36, p=.55.
For an outgroup cheater, participants’ ratings of data quality did not differ reliably
between the two authorities: F(1,54)=.32, p=.58.
