Captions on Tables Not going on Top Latex - formatting

Question

For some reason, my captions for my tables are not going on the top of the table as I would like. Instead they are defaulting to the bottom of the table.
Does anybody have any ideas for changes I can make to ensure the caption is on the top? I suspect there is something going on in my preamble that I'm missing.
Here is my code for the table
\caption{Summary Statistics}
\centering
\begin{tabular}{l c c c}
\hline
\textbf{Variable} & Min & Max & Mean \\
\hline
Racial Diversity & 0.01 & 0.52 & 0.23 \\
\hline
\multicolumn{4}{l}{%
\begin{minipage}{7cm}%
\small
%Table includes all variables in the analyses in Table 3 \& 4.
\end{minipage}%
}\\
\label{descrip}
\end{tabular}
\end{table}

Answer 1

Captions of tables are above the table by default. However amongst the hundreds of packages you load, many of them multiple times and with contradictory options that result in errors that prevent compilation of your document, is the floatrow package. Either remove it or configure it to place the caption above:
\documentclass{article}
\usepackage{floatrow}
\floatsetup[table]{capposition=above}
\begin{document}
\begin{table}
\caption{Summary Statistics}
\centering
\begin{tabular}{l c c c}
\hline
\textbf{Variable} & Min & Max & Mean \\
\hline
Racial Diversity & 0.01 & 0.52 & 0.23 \\
\hline
\multicolumn{4}{l}{%
\begin{minipage}{7cm}%
\small
%Table includes all variables in the analyses in Table 3 \& 4.
\end{minipage}%
}\\
\label{descrip}
\end{tabular}
\end{table}
\end{document}
