Help Recreating a Table

Question

I am trying to recreate this table using LaTeX.

I want to additionally align the decimals. I have tried using this code to do so.

\begin{frame}
\frametitle{Table}
\begin{table}
\begin{tabular}{l *{4}{d{3.3}} }
\toprule
Variable & Weighted Test Statistic  & Unweighted p-value & Weighted Test Statistic  & Unweighted p-value\\
\midrule
Attendance Rate&0.55&0.0875&2.15&$<$0.0001\\
Test Average&4.14&0.0320&4.68&0.0080\\
Final Exam&4.12&0.0022&1.99&0.1590\\
\makecell{Data Analysis \\ Assignment Average}&20.98&$<$0.0001&17.42&$<$0.0001\\
Quiz Average&3.88&0.0035&2.33&0.0399\\
\bottomrule
\end{tabular}
\caption{Kruskal-Wallis Tests by Semester}
\end{table}

\end{frame}

This code created the following table. There are several things I would like to fix. Namely

• Adding fall and spring panels like in the original table
• Aligning the values associated with the "Data Analysis Assignment Average" at the top of that row
• Fixing the < signs
• Fixing the headings so that they can be within the bounds of a PowerPoint slide. I tried using the makecell{.} function but it didn't work the same as with the \midrule components.

Note: I wasn't sure what to title this question so feel free to change it.

Edit:

Using Zarko's code, I get the following.

Answer 1

with tabularx, siunitx and makecell packages:

\documentclass{beamer}
\usepackage{booktabs, makecell, multirow, tabularx}
\renewcommand\theadfont{\footnotesize}
\renewcommand\theadgape{}
\usepackage{siunitx}

\begin{document}

\begin{frame}
    \begin{table}
\caption{Kruskal-Wallis Tests by Semester}
\renewcommand{\arraystretch}{1.2}
\setlength\tabcolsep{2pt}
\small
\begin{tabularx}{\textwidth}{@{}
                            >{\raggedright\linespread{0.84}\selectfont}X
                            *{2}{S[table-format=2.2]
                                  S[table-format=1.4,
                                    table-comparator=true]}
                            @{}}
    \toprule
\multirow[b]{3}{=}{Variable}
    &   \multicolumn{2}{c}{Fall} &  \multicolumn{2}{c}{Spring}  \\
    \cmidrule(r){2-3} \cmidrule(l){4-5}
    &   {\thead{Weighted\\ Test Statistic}}
        &   {\thead{Unweighted\\ p-value}}
            &   {\thead{Weighted\\ Test Statistic}}
                &   {\thead{Unweighted\\ p-value}}           \\
    \midrule
Attendance Rate                     &  0.55 &  0.0875 &  2.15 & <0.0001\\
Test Average                        &  4.14 &  0.0320 &  4.68 &  0.0080\\
Final Exam                          &  4.12 &  0.0022 &  1.99 &  0.1590\\
Data Analysis Assignment Average    & 20.98 & <0.0001 & 17.42 & <0.0001\\
Quiz Average                        &  3.88 &  0.0035 &  2.33 &  0.0399\\
    \bottomrule
\end{tabularx}
    \end{table}
\end{frame}
\end{document}

Answer 2

Here my suggestions.

I have not met the point two. It seems more elegant to me aligned at the bottom, or as showed here, aligned at the middle. But if you disagree, just change the m column by a p. Anyway, with p,m or b the main point is that without awful the horizontal rows, this table needs some extra vertical space between rows to mark clearly where start/end the text of the multiline cell. Otherwise, the "Variable" column is a mess.

\documentclass{beamer}
\usepackage{booktabs,tabularx,dcolumn}
\newcolumntype{d}{D{.}{\cdot}{-1}}
\begin{document}
\begin{frame}
\begin{table}
\caption{Kruskal-Wallis Tests by Semester}
\footnotesize\tabcolsep0em
\renewcommand{\arraystretch}{1.5}
\begin{tabularx}{\textwidth}{>{\raggedright}m{10em}dddd}\toprule & 
\multicolumn{2}{c}{Fall} &
\multicolumn{2}{c}{Spring} \\
\cmidrule(r){2-3}
\cmidrule(l){4-5}
\multicolumn{1}{X}{\leavevmode\newline Variable} & 
\multicolumn{1}{X}{\centering Weighted Test Statistic}  & 
\multicolumn{1}{X}{\centering Unweighted p-value} & 
\multicolumn{1}{X}{\centering Weighted Test Statistic}  & 
\multicolumn{1}{X}{\centering Unweighted p-value} \tabularnewline
\cmidrule(r){1-1}
\cmidrule(rl){2-2}
\cmidrule(rl){3-3}
\cmidrule(rl){4-4}
\cmidrule(rl){5-5}
Attendance Rate                     &  0.55 &  0.0875 &  2.15 & <0.0001\\
Test Average                        &  4.14 &  0.0320 &  4.68 &  0.0080\\
Final Exam                          &  4.12 &  0.0022 &  1.99 &  0.1590\\
Data Analysis Assignment Average    & 20.98 & <0.0001 & 17.42 & <0.0001\\
Quiz Average                        &  3.88 &  0.0035 &  2.33 &  0.0399\\
\bottomrule
\end{tabularx}
\end{table}
\end{frame}
\end{document}

Answer 3

This might work for your purposes. I used the article class for this but I think you can change it to beamer and use the \frametitle{} option in lieu of the caption and you can adjust the font size as needed using \footnotesize or anything else that can fit the dimensions of the slide. In addition, you can add the \begin{frame} and \end{frame} to the beginning and end of the table chunk of code.

\documentclass{article}

\usepackage{fullpage}
\usepackage{tabulary}
\usepackage{booktabs}
\begin{document}

\begin{table}
    \caption{Kruskal-Wallis Tests by Semester}
    \begin{tabulary}{\linewidth}{LCCCC}
        \\
        \hline
        & \multicolumn{2}{c}{Falll}&\multicolumn{2}{c}{Spring} \\
        \hline
        Variable & Weighted Test Statistic  & Unweighted p-value & Weighted Test Statistic  & Unweighted p-value\\
        \hline
        Attendance Rate&0.55&0.0875&2.15&$<$0.0001\\
        Test Average&4.14&0.0320&4.68&0.0080\\
        Final Exam&4.12&0.0022&1.99&0.1590\\
        Data Analysis&&&&\\ 
        Assignment Average&20.98&$<$0.0001&17.42&$<$0.0001\\
       Quiz Average&3.88&0.0035&2.33&0.0399\\
       \hline 
    \end{tabulary}
\end{table}

\end{document}

Edit:

For beamer class,

\begin{frame}
\footnotesize %Or whatever other size you need
\frametitle{MY TABLE} %Frame Title
\begin{table}
    \caption{Kruskal-Wallis Tests by Semester}
    \begin{tabulary}{\linewidth}{LCCCC}
        \\
        \hline
        & \multicolumn{2}{c}{Falll}&\multicolumn{2}{c}{Spring} \\
        \hline
        Variable & Weighted Test Statistic  & Unweighted p-value & Weighted Test Statistic  & Unweighted p-value\\
        \hline
        Attendance Rate&0.55&0.0875&2.15&$<$0.0001\\
        Test Average&4.14&0.0320&4.68&0.0080\\
        Final Exam&4.12&0.0022&1.99&0.1590\\
        Data Analysis&&&&\\ 
        Assignment Average&20.98&$<$0.0001&17.42&$<$0.0001\\
       Quiz Average&3.88&0.0035&2.33&0.0399\\
       \hline 
    \end{tabulary}
\end{table}
\end{frame}

I hope this helps!
