Moyenne et r\u00e9partition<\/h2>\n

En l\u2019absence d\u2019informations suppl\u00e9mentaires, impossible de r\u00e9pondre \u00e0 cette question. Pour cela, il faut conna\u00eetre la r\u00e9partition de la taille des Fran\u00e7aises. De plus, la question est mal formul\u00e9e\u00a0: la Fran\u00e7aise moyenne est un mythe\u00a0\u2026 il est pr\u00e9f\u00e9rable de parler de la taille moyenne des Fran\u00e7aises. En fait, elles se r\u00e9partissent en 25\u00a0% de petites (1 m\u00e8tre 54 en moyenne), 50\u00a0% de moyennes (1 m\u00e8tre 63 en moyenne) et 25\u00a0% de grandes (1 m\u00e8tre 72 en moyenne). La r\u00e9partition exacte suit une courbe en forme de cloche comme c\u2019est le cas g\u00e9n\u00e9ralement quand on \u00e9tudie une population homog\u00e8ne sous un certain crit\u00e8re.<\/span><\/span><\/p>\n
