ABSTRACT

The minimum and the adequate number of participants in experiments with maps can vary significantly according to the characteristics of the participants, the maps, and especially the test’s purpose. In this sense, the estimation of the adequate number of participants employed in carrying out tests involving map users bases the problem of this research. The study’s hypothesis presupposes that it is possible to establish the number of participants for each group of methods of experiments with similar characteristics that group the tests. To this end, to compare terms found in the Web of Science database with those informed in the title, abstract, introduction, and methodology of 200 scientific articles published in the area of cartography, whose subject is related to map users, the research performed an analytical review of the works. As a result, the analysis made it possible to select 85 publications, such as adequacy to the subject of study, according to the methods used. The results obtained from the research make it possible to define the number of participants according to the purpose of the applied test when evaluating maps.

RÉSUMÉ

Les nombres de participants minimum et approprié pour réaliser des expérimentations sur des cartes peuvent varier de façon significative en fonction des caractéristiques des participants, des cartes et surtout de l'objectif du test. C'est pourquoi l'estimation du nombre approprié de participants requis pour conduire un test impliquant des utilisateurs de cartes est le cœur de cette recherche. L'hypothèse de l'étude présuppose qu'il est possible de fixer le nombre de participants pour chaque type de méthodes expérimentales avec des caractéristiques similaires qui permettent de regrouper les tests. Pour cela nous avons effectué une analyse critique de travaux pour comparer les termes trouvés dans la base de données Web Of Science avec ceux trouvés dans les titres, résumés, introductions et méthodologies de 200 articles scientifiques publiés dans le domaine de la cartographie sur le sujet des utilisateurs de cartes. Comme résultat, l'analyse a permis de sélectionner 85 publications, en adéquation au sujet de l'étude, en fonction de la méthode utilisée. Les résultats obtenus à partir de cette recherche permettent de définir le nombre de participants en fonction de l'objectif du test appliqué lors de l'évaluation des cartes.
