Popis funkce pro v\u00fdpo\u010det variance v Excelu a Google Sheets<\/h2>\n

Funkce, kterou zde zkoum\u00e1me, slou\u017e\u00ed k v\u00fdpo\u010dtu vzorkov\u00e9 variance sady \u010d\u00edseln\u00fdch hodnot. Variance je statistick\u00e1 m\u00edra, kter\u00e1 ur\u010duje, jak \u0161iroce se jednotliv\u00e9 \u010d\u00edsla v datov\u00e9 sad\u011b rozkl\u00e1daj\u00ed kolem jejich pr\u016fm\u011bru. Tato funkce je zvl\u00e1\u0161t\u011b u\u017eite\u010dn\u00e1, pokud prov\u00e1d\u00edme anal\u00fdzu na vzorku dat z v\u011bt\u0161\u00edho souboru.<\/p>\n

Syntaxe funkce v MS Excel:<\/strong><\/p>\n

Je kl\u00ed\u010dov\u00e9, aby tyto hodnoty reprezentovaly n\u00e1hodn\u011b vybran\u00fd vzorek z celkov\u00e9 populace.<\/p>\n
