Analysis of covariance was selected in this case because of the covariates' preexisting differences.
Analysis of covariance necessitates homogeneity of slopes across the experimental groups.
The Second Edition of Analysis of Covariance and Alternatives sheds new light on its topic, offering in-depth discussions of underlying assumptions, comprehensive interpretations of results, and comparisons of distinct approaches.

provides an applied and comprehensive treatment of the analysis of covariance, which he says is one of the least understood and most misused of all statistical methods.
Descriptive analyzes were used to determine mean and standard deviation and inferential statistics were used in the analysis of covariance and software SPSS18.
They assume readers have a basic understanding of generalized linear models, such as multiple regression and logistic regression, but do discuss some basic methods in great detail, such as Pearson's correlation and the analysis of covariance.
An analysis of covariance demonstrated a statistically significant difference from placebo on the Sum of Pain Intensity Differences (SPID) over 50 hours using LOCF (last observation carried-forward) as the imputation method, however, the results were not statistically significant using LOCF/BOCF (baseline observation carried-forward), the primary endpoint.
