label arrow for tree diagram

Question

Kindly I want to ask how I can plot a diagram like the attached one on latex?

Thanks

Here is what I have already done:

   \begin{tikzpicture}[>=latex']
    \tikzset{block/.style= {draw,rectangle,align=center,minimum width=2cm,minimum height=1cm}}
    \node [block]     (n0)  {Shooping intention};
    \node [block, above left =3cm of n0](n1)   {Country};
    \node [block, below =3cm of n1 ]       (n2)     {Gastronomic culture };
    \node [block, below =3cm of n2]      (n3)        {Product Evaluation};
   \node [block, right =3cm of quality](n4)   {Gender};

\path[draw]
    (n0.west) edge[-&gt;]  (n1.east) 
    (n0.west) edge[-&gt;] (n2.east)
    (n0.west) edge[-&gt;] (n3.east)
    (n0.east) edge[-&gt;] (n4.west)
;

\end{tikzpicture}

Just I want to know how I can put the number on the arrow?

Welcome to TeX.SX! Questions about how to draw specific graphics that just post an image of the desired result are really not reasonable questions to ask on the site. Please post a minimal compilable document showing that you've tried to produce the image and then people will be happy to help you with any specific problems you may have. See minimal working example (MWE) for what needs to go into such a document. — TobiBS, Aug 09 '20 at 14:32
Thank you André. But how I can put a label on the arrow? This is my problem — user222105, Aug 09 '20 at 14:34
@user222105 You can use the AndréC's answer for example: https://tex.stackexchange.com/questions/463640/how-to-duplicate-a-bent-line-and-change-its-position-keeping-its-arrow-using-tik — Sebastiano, Aug 09 '20 at 15:09

For fun, a short pstricks code reproducing (more or less faithfully) the image in the O.P.

\documentclass{article}%[border=12pt]{standalone}
\usepackage{newtxtext, newtxmath} 
\usepackage[usestackEOL]{stackengine} 
\usepackage{bigstrut}
\setlength{\bigstrutjot}{2ex}
 \usepackage{pst-node}
\begin{document}
%
\psset{arrows=->, arrowinset=0.15, linewidth=0.5pt, nodesep=3pt, labelsep=2pt}
\small
 \begin{psmatrix}[mnode=oval, colsep=3cm, rowsep=1cm]
%%% nodes
[name=Co] \Centerstack{Country\of origin} \
[name=Ga]\Centerstack{Gastronomic\culture} & [name=Si]\Centerstack{Shopping\intention} & [name=Ge]\Centerstack{Gender\bigstrut[b] } \
[name=Pe]\Centerstack{Products\evaluation}
 %%% arrows
\psset{arrows=->, arrowinset=0.15, arrowsize=2pt, nodesep=0pt, npos=0.4}
  \ncline{Co}{Si}\naput[nrot=:U]{$ 0.166^$}
  \ncline{Ga}{Si}\naput{$ 0.280^{}$}
  \ncline{Pe}{Si}\naput[nrot=:U]{$ 0.256^{}$}
  \ncline{Ge}{Si}\nbput{$- 0.224^{**}$}
%%% misc
\uput{2.5em}d{$\mathrm{R}^2=0.236$}
\uput{2.67em}d{\rnode{Co}{Control}}
\uput{1.5em}u{\pnode{U}}
\ncbox[nodesep=.2cm,boxsize=0.85, linearc=.1, linestyle=dashed, dash =4pt 2.5pt]{Co}{U}
\end{psmatrix}
\end{document}

Different ways of putting a label on an arrow are as below

\begin{tikzpicture}[>=latex',  node distance=3cm and 4cm, ]
\tikzset{block/.style= {draw,rectangle,align=center,minimum width=2cm,minimum 
height=1cm}}
\node [block]                   (n0)  {Shooping intention};
\node [block, above left =of n0](n1)   {Country};
\node [block, below =of n1 ]     (n2)     {Gastronomic culture };
\node [block, below =of n2]      (n3)        {Product Evaluation};
\node block, right =of n0   {Gender};
\path[draw]
(n0.west) edge[->]nodepos=0.5,above,sloped,{XXX}  (n1.east) 
(n0.west) edge[->]nodemidway, label=90:pqrs,{} (n2.east)
(n0.west) edge[->]nodemidway, label={[label distance=-4pt,rotate=45]135:$555$}{} 
(n3.east)
(n0.east) edge[->] nodemidway, label=-90:abcd,{}(n4.west)
;
\end{tikzpicture}

One more, more complete mimic of the image shown in your question, using tikz package:

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows.meta,
                fit,
                positioning,
                quotes,
                shapes.geometric}
\begin{document}
    \begin{tikzpicture}[
node distance = 8mm and 24mm,
   arr/.style = {-Stealth, semithick},
     E/.style = {ellipse, draw, semithick,
                 text width=#1, aspect=1.2, align=center,
                 inner xsep=0pt, outer sep=0pt},
   E/.default = 5.4em,
every edge quotes/.style = {auto, font=\footnotesize, inner sep=2pt, sloped},
every label/.style = {label distance=3pt, inner sep=2pt,
                      font=\small}

                        ]
\node (n0)  [E]                 {Country of origin};
\node (n1)  [E, above=of n0]    {Gastronomic culture};
\node (n2)  [E, below=of n0]    {Product Evaluation};
\node (n3)  [E, label=below:{$R^2=0.235$},
             right=of n0]       {Shooping intention};
\node (n4)  [E=3em, label={[name=n4L]below:Control},
             right=of n3]       {Gender};
\node [draw, dashed, fit=(n4) (n4L)]  {};
%
\draw   (n1) edge["$0.166^{*}$"]    (n3)
        (n0) edge["$0.280^{**}$"]   (n3)
        (n2) edge["$0.256^{***}$"]  (n3)
        (n3) edge["$-0.224^{***}$"] (n4);
    \end{tikzpicture}
\end{document}

In comparison to your MWE are added labels to arrows using quotes library, nodes have elliptic shapes, added are labels to nodes.
