Analysis of variance and its applications in Macau educational resarches

In 2012, Macau government approved and passed the “System Framework for Private School Teaching Staff of Non-tertiary Education” in the legislative council. It is aimed at improving non-tertiary teachers’ professionalism in terms of setting hierarchies and provides training continuously. Teachers having a high level of research capacity can improve and solve education issues in Macau. Education Statistics are one of the important methods in research capacity. To develop this idea, therefore, my topic is “Analysis of variance and Its Applications in Macao Educational Researches”.In this paper a series of statistical methods will be studied, namely, ANOVA, ANCOVA and MANCOVA. They can be used to analyze multivariate data. Knowledge of these techniques will enable researchers to investigate and answer a vast array of research questions. This paper will apply also a real example in educational field in order to explain the manipulation of ANOVA, ANCOVA and MANOVA for data analysis.
