When analyzing assessment data based on grouping and gender, a one-way analysis of covariance
(ANCOVA) was performed with the independent variables, grouping and gender, including cluster and noncluster/male and female.
We also found significant differences between the four racial/ethnic groups on the MRNI-R Total Scale, through univariate analysis of covariance
by race/ethnicity on the MRNI-R Total Scale.

Using univariate analysis of covariance
and multivariate analysis of variance to compare between-group differences in score changes relative to baseline, the investigators determined that, in the chair rise, the functional training group had significantly more improvement in energy expenditures and compensations by increasing ankle energy expenditure and decreasing back compensation, compared with the strength training group.
We compared assessments of cognitive function and fatigue using an analysis of covariance
. MS subjects on CNS-active medication had greater impairment on measures of processing speed, sustained attention, and fatigue than those not on these medications.
When we compared the slopes and intercepts of these 2 linear regression lines by the method described by Zar (9), a method equivalent to analysis of covariance
, the 2 regression lines showed significantly different intercepts (P <0.001), whereas we found no significant difference between the slopes (P = 0.23; GraphPad Prism 4 Software).
Significance test and goodness-of-fit in the analysis of covariance
The data collected on both instruments were analyzed using an analysis of covariance
(ANCOVA) in which the dependent variable was learner perceptions as measured by the posttest and the covariate were learner perceptions as measured by the pretest.
Due to the potential for initial motor skills differences, the author employed analysis of covariance
as a means for controlling for initial group differences on the PDMS-2.
The average of the right and left limbs for the healthy group was compared to each limb of the stroke group using an analysis of covariance
with gait speed as the covariant.
