Social supportSocial support is the perception and actuality that one is cared for, has assistance available from other people, and most popularly, that one is part of a supportive social network. These supportive resources can be emotional (e.g., nurturance), informational (e.g., advice), or companionship (e.g., sense of belonging); tangible (e.g., financial assistance) or intangible (e.g., personal advice). Social support can be measured as the perception that one has assistance available, the actual received assistance, or the degree to which a person is integrated in a social network.
Test statistiqueEn statistiques, un test, ou test d'hypothèse, est une procédure de décision entre deux hypothèses. Il s'agit d'une démarche consistant à rejeter ou à ne pas rejeter une hypothèse statistique, appelée hypothèse nulle, en fonction d'un échantillon de données. Il s'agit de statistique inférentielle : à partir de calculs réalisés sur des données observées, on émet des conclusions sur la population, en leur rattachant des risques d'être erronées. Hypothèse nulle L'hypothèse nulle notée H est celle que l'on considère vraie a priori.
