These outliers were detected using a statistical method
(i.e. Mahalanobis distance). The Mahalanobis distance values should be lower than
the critical x 2 value of 16.81 at an a level of 0.01. An examination of the Mahalanobis
distance values indicated that these 20 responses were outliers among the variables.
Therefore, 433 returns were used for analysis, yielding a 66.62 percent response rate
