How to number the chapter of references and appendixes in Table Of Contents

Question

Partial code of my main file:

\pagenumbering{arabic}
\setlength{\headheight}{12pt}
\pagestyle{plain}
\include{chap1} 
\include{chap2}
\include{ch3}
\include{Experiment} % Extract Correlation
\addcontentsline{toc}{chapter}{ \hskip 4em References}
\bibliographystyle{apacite}
\bibliography{SpecialStudy}

\newpage
\pagestyle{plain}
\theappendix
\addcontentsline{toc}{chapter}{ \hskip 4em Appendixes}
\include{appendixA_refactoring_approach}

With this code I'll get:

     // bah bah bah
3    Test0
     3.1 hello
     3.2 hello2
4    Test1
     4.1 Intro
     4.2 Experiment Objective
     4.3 Research Question
     References 
     Appendixes

I really want to number References and Appendixes like below. How should I code?

3    Test0
     3.1 hello
     3.2 hello2
4    Test1
     4.1 Intro
     4.2 Experiment Objective
     4.3 Research Question
5    References
6    Appendixes 

Answer 1

For the standard classes have a look at the tocbibind package. Other classes like memoir or those from the KOMA Script bundle have built-in features. For the appendix you probably need the appendix package in some cases.

Answer 2

If you use the package apacite, you can have a numbered bibliography by

\usepackage[numberedbib]{apacite}

For the appendices, I suggest

\chapter{Appendices}

and then using \section to start each appendix. My studies of Latin make me prefer this form of the plural.
