Bonjour,<\/p>\n

<\/p>\n

Je travaille sur un projet d’analyse de donn\u00e9es portant sur les habitudes de lecture d’\u00e9tudiants universitaires. J’ai collect\u00e9 un ensemble de donn\u00e9es contenant des informations vari\u00e9es : le genre litt\u00e9raire pr\u00e9f\u00e9r\u00e9 (roman, essai, po\u00e9sie, etc.), le nombre de livres lus par an, le temps moyen pass\u00e9 \u00e0 lire par semaine, et le type de support de lecture privil\u00e9gi\u00e9 (livre papier, liseuse, application sur t\u00e9l\u00e9phone).<\/p>\n

<\/p>\n

Mon objectif est d’identifier des corr\u00e9lations entre ces diff\u00e9rentes variables, par exemple si les \u00e9tudiants qui lisent plus de livres par an pr\u00e9f\u00e8rent un certain genre litt\u00e9raire ou utilisent un type de support sp\u00e9cifique. Je souhaite \u00e9galement segmenter les \u00e9tudiants en groupes en fonction de leurs habitudes de lecture afin d’\u00e9tablir des profils type.<\/p>\n

<\/p>\n

Pour cela, je suis \u00e0 la recherche de m\u00e9thodes d’analyse statistique appropri\u00e9es pour ce type de donn\u00e9es. Plus pr\u00e9cis\u00e9ment, quelles m\u00e9thodes me conseillez-vous pour:<\/p>\n

<\/p>\n

    <\/p>\n
  1. \n

    Identifier les corr\u00e9lations<\/strong> entre les variables qualitatives (genre litt\u00e9raire, type de support) et quantitatives (nombre de livres lus, temps de lecture) ? Est-ce que les tests du chi-deux, ANOVA, ou d’autres techniques seraient les plus pertinents dans ce contexte ? Si oui, comment les interpr\u00e9ter concr\u00e8tement dans le cadre de mon \u00e9tude ?<\/p>\n

    \n<\/li>\n

    <\/p>\n

  2. \n

    R\u00e9aliser une segmentation des \u00e9tudiants<\/strong> en fonction de leurs habitudes de lecture ? Quelles m\u00e9thodes de clustering (K-means, clustering hi\u00e9rarchique, etc.) seraient les plus adapt\u00e9es, compte tenu de la nature de mes donn\u00e9es (variables mixtes) ? Comment d\u00e9terminer le nombre optimal de clusters ? Quels outils de validation me permettraient d’\u00e9valuer la qualit\u00e9 de la segmentation obtenue ?<\/p>\n

    \n<\/li>\n

    <\/p>\n

  3. \n

    Visualiser efficacement les r\u00e9sultats<\/strong> de ces analyses afin de les rendre compr\u00e9hensibles pour un public non-statisticien ? Quels types de graphiques (nuages de points, diagrammes en barres, heatmaps, etc.) seraient les plus appropri\u00e9s pour illustrer les corr\u00e9lations identifi\u00e9es et les profils de lecteurs r\u00e9sultant de la segmentation ?<\/p>\n

    \n<\/li>\n

    \n<\/ol>\n

    <\/p>\n

    Enfin, existe-t-il des biblioth\u00e8ques ou des packages sp\u00e9cifiques dans R ou Python particuli\u00e8rement recommand\u00e9s pour r\u00e9aliser ces analyses ?<\/p>\n

    <\/p>\n

    Merci d’avance pour vos conseils et suggestions !<\/p>\n
