Popis a syntaxe funkce pro zkosen\u00ed distribuce<\/h2>\n

Funkce SKEW, dostupn\u00e1 v Microsoft Excel a Google Sheets, se pou\u017e\u00edv\u00e1 k v\u00fdpo\u010dtu m\u00edry zkosen\u00ed neboli skewness sady dat. Skewness je statistick\u00fd ukazatel, kter\u00fd m\u011b\u0159\u00ed asymetrii distribuce dat okolo st\u0159edn\u00ed hodnoty. Pokud je hodnota kladn\u00e1, data jsou zkosen\u00e1 vpravo; je-li z\u00e1porn\u00e1, jsou zkosen\u00e1 vlevo. Hodnota bl\u00edzko nule nazna\u010duje, \u017ee distribuce dat je symetrick\u00e1.<\/p>\n
