The distribution of data from each condition in Experiment 2B was tested for
normality using a Shapiro-Wilk test. For experiment 2B, the Shapiro-Wilk test of
normality indicates that the two distributions, one from each condition, do not differ
significantly from a normal distribution, both p > .05. For this reason, it was appropriate
to make inferences on the data by using an ANOVA.
Data from this experiment was further analyzed using a Wilcoxon Signed Ranks
Test. This was an important test to conduct for this particular experiment because the
Shapiro-Wilkes test might not be accurate when sample size is small. In this experiment,
the sample size was 8 participants per condition. Like the ANOVA used to compare the
