The statistical significance was determined using Fisher's exact two-tailed test
. For example, for the 2009 release of the Specimen hierarchy, approximately 20% of its concepts were overlapping.
(b) ***, ** and * denote statistical significance at the 1%, 5% and 10% level using two-tailed tests
Using two-tailed tests
for the emotional exhaustion dimension, the significant predictors were emotional contagion (standardized [beta]=1.40, p<.05) and the interaction term between overidentification tendency and emotional contagion (standardized [beta]=1.60, p<.01).
In Case 1, Type-I error rates of two-tailed tests
were determined at significance levels 1 - [alpha] = .90, .95, and .99 by computing the proportion of occasions (across the set of 20,000 tables) in which the statistic value exceeded either of the critical limits [b'.sub.[alpha]/2] and [b'.sub.1-[alpha]/2] for a two-sided size-[alpha] test, where these critical limits were determined for each table by obtaining coefficients [gamma] and [delta] through Equations (5) and (6) using the data from the current table and then transforming the limits in Appendix B through these coefficients.
Since the signs on the partial derivatives for the first four explanatory variables (UR, ME, HS&M, AGE65&M) are expected to be qualitatively the same in each equation for both males and females, it follows that the coefficients estimated for each of these variables must be subjected to a two-tailed test
in order to determine whether there is a quantitative gender difference in the response to each of these variables (each of which is expressed according to gender).
(18) This is significantly different from the 33 of 66 (or 50%) selecting trust in the regular version of the trust game (with a p value of 0.069 in a two-tailed test
Significance levels correspond to a two-tailed test
of the null hypothesis that the coefficient equals zero.
This is a two-tailed test
, so at [alpha] = 0.05, the tabulated t statistic is 4.303.
