Clay content varied between and within sites: therefore, analysis of covariance
was used to determine if measured differences in soil organic carbon and soil bulk density were increased by including the effect of clay content as a covariate.
Lengths were transformed to logarithms and an Analysis of Covariance
to determine slope differences was employed.
Analysis of covariance
(ANCOVA) was utilized to test questions one to four to determine whether significant differences existed in gross motor skills, object manipulation, stationary skills, and locomotion for preschool children between the two groups.
While controlling for background variables, analysis of covariance
was used to test for potential interaction between support and monitoring across the adolescent variables.
Analyzing psychological data by structural analysis of covariance
We used analysis of covariance
with litter size as a covariate to test the juvenile weight and length data.
One such alternative is provided by analysis of covariance
structures (Aigner et at.
A 2 (threat) x 2 (efficacy) analysis of covariance
(ANCOVA) method was performed to test the hypotheses.
Least squares regression and analysis of covariance
were used to compare slopes and elevations for bivariate comparisons between different groups.
10) Analysis of covariance
(ANCOVA) was used as the statistical method because auditors' frequency of using ratio analysis was not distributed evenly across the experimental cells, despite random assignment to treatment conditions.
