Cet article est une ébauche à compléter. Une ébauche est une entrée ayant un contenu (très) maigre et qui a donc besoin d'un auteur.
Pour le moment, cet article n'explique pas l'analyse de régression. On montre juste comment produire des graphiques avec SPSS !
Créer un nuage de points
Comment visualiser une simple régression linéraire avec SPSS ?
Modèle exemple
PISA 2012, élèves Suisses.
Question: Est-ce qu'on prédire l'angoisse des maths avec l'intérêt pour les maths ?
- x = intérêt pour les maths (var explicative)
- y = angoisse des maths (à expliquer)

L'outil Chart Builder
En Anglais:
- Menu Charts -> Chart Builder
En français:
- Menu Graphiques -> Générateur de graphiques
Ajouter la droite de régression linéaire avec l'outil Chart Editor
- Une fois que vous avez produit un graphique avec le générateur de graphiques, il faut double cliquer dessus (donc pas dans le chartbuilder, mais dans la sortie !!!)
- Vous voyez maintenant le Chart Editor, un outil qui vous permet de manipuler tous les graphiques produits par SPSS. Encore fois: Cet outil n'est pas dans le menu, il faut double-cliquer sur une sortie !
- Choisir l'icône Add Fit line at total (Ajouter une courbe d'ajustement au total). Une fenêtre "propriétés" va apparaître
- Dans la fenêtre propriétés, choisir "linéraire" (c.f. copie d'écran suivante)
Résultat
Effectivement: quand on a plus d'intérêt pour les maths, on a moins peur (donc c'est une relation statistique, ce qui ne vaut pas cause....)
On peut aussi créer des graphiques un peu plus sophistiqués:
Pour aller plus loin
Dans l'outil "Chars -> Chart Builder " choisir "Grouped scatter" au lieu de "simple scatter". Ensuite ajouter une variable catégorielle (gender ici).
Résultat: Chez les filles, l'effet est un peu plus fort.
- Dans le Chart editor ajouté des courbes: Add fit lines to subgroupes. Choisir "Loess".
- Aggrandi le graphique
Refaire les indices
Les indices PISA sont difficiles à interpréter car ils sont (1) standardisés et (2) calculés avec une méthode de prédiction probabiliste. Donc je conseille de les refaire plus simplement, même s'il peut y avoir des objections méthodologiques:
Les 2 groupes de variables sont mesurées avec une simple échelle Likert:
