Missing data is a common issue in research that, if improperly handled, can lead to inaccurate conclusions about populations. A variety of statistical techniques are available to treat missing data. Some of these are simple while others are conceptually and mathematically complex. The purpose of this paper is to provide the novice researcher with an introductory conceptual overview of the issue of missing data. The authors discuss patterns of missing data, common missing-data handling techniques, and issues associated with missing data. Techniques discussed include listwise deletion, pairwise deletion, case mean substitution, sample mean substitution, group mean substitution, regression imputation, and estimation maximization.

Les données manquantes posent un problème fréquent en recherche; s'il n'est pas traité correctement, il peut fausser les conclusions concernant une population. Il existe un ensemble de méthodes statistiques permettant d'interpréter les données manquantes, certaines simples, et d'autres complexes, sur le plan théorique et mathématique. Le présent article propose une vue d'ensemble du problème des données manquantes à l'intention des chercheurs débutants. Les auteurs expliquent les modèles de données manquantes, discutent des questions qu'elles soulèvent et présentent certaines méthodes de traitement courantes. Parmi les techniques abordées, on compte la suppression dans la liste (listwise suppression), la suppression par paires (pairwise suppression), la substitution moyenne par cas, par échantillon ou par groupe, l'imputation par régression et la maximisation de l'estimation.

    Currently published issues of the CJNR (1969-2015) are being moved to the McGill online archives where they will be hosted in perpetuity. This migration should be completed by Spring 2016. During this transition, all issues of CJNR remain accessible to our readers as before:

    1) Past issues of CJNR from 2003 to December 2015 through ingentaconnect.

    2) Issues from 2002 to 1969 can be accessed through the CJNR digital archive.

    We understand that this is a significant change. Please be confident that all parties are working diligently to make this a seamless transition that will further advance the scope and impact of CJNR.

    Thank you.
