Funkce \u010cETNOST<\/strong> je efektivn\u00ed statistick\u00fd n\u00e1stroj v MS Excel a Google Sheets, kter\u00fd umo\u017e\u0148uje zjistit, jak \u010dasto se jednotliv\u00e9 hodnoty objevuj\u00ed v dan\u00e9m datasetu. Tato funkce je velmi vhodn\u00e1 pro anal\u00fdzu velk\u00fdch mno\u017estv\u00ed dat a poskytuje mo\u017enost vizualizace distribuce hodnot v r\u016fzn\u00fdch intervalech.<\/p>\n

Jak funkci definovat a pou\u017e\u00edvat<\/h2>\n

Funkce \u010cETNOST<\/code> vy\u017eaduje dva argumenty: data_pole<\/em> a t\u0159\u00eddy_pole<\/em>. Data_pole<\/em> obsahuje hodnoty ke zpracov\u00e1n\u00ed, zat\u00edmco t\u0159\u00eddy_pole<\/em> definuje intervaly, ve kter\u00fdch chceme hodnoty analyzovat.<\/p>\n

Syntaxe funkce je n\u00e1sleduj\u00edc\u00ed:<\/p>\n
