Tutoriels de statistiques - mathcracker.com

MATHCRACKER propose une grande variété de calculateurs de statistiques, qui effectueront des calculs pas à pas pour vous.De telles calculatrices viennent sous toutes les formes et formes, certaines sont très simples (comme par exemple, simple, simple Combinatoire de coefficient de Calculs de coefficient) et certains comportent des calculs élaborés (comme un test statistique non paramétrique).

Un grand avantage de nos calculatrices / solveurs en ligne est que nous essayons de fournir, dans la mesure du possible, un détail complet de la procédure à suivre pour arriver à la solution requise. Nous croyons que montrer toutes les étapes de la façon dont on est arrivée à la solution est la meilleure façon (et parfois la seule façon) d'apprendre un sujet.

Il existe de nombreuses calculatrices de probabilité (y compris des calculatrices pour les distributions les plus courantes, telles que la normale, la distribution de T, la distribution F, etc.), une Sélection complète des solveurs de test d'hypothèse, pour des tests paramétriques et non paramétriques.

Comment trouver la calculatrice de statistiques que je recherche?

Consultez notre liste ci-dessous sur STATS Solvers ou vous pouvez également utiliser la zone de recherche fournie pour trouver la calculatrice exacte que vous recherchez.Chaque solveur viendra avec des instructions claires sur la manière dont le solveur doit être utilisé.De plus, certaines calculatrices auront des vidéos disponibles qui vous aideront à procéder si vous avez des problèmes.

Notre objectif est d'avoir la collection la plus complète de calculatrices de mathématiques en ligne, et quand je dis que je veux dire que nous n'avons pas que des calculatrices de statistiques, mais aussi une algèbre, une probabilité et de nombreux autres sujets.S'il y a un solveur que vous ne trouvez pas sur notre site et que vous souhaitez voir inclus ici, n'hésitez pas à NOUS CONTTATEUR .
