Funkce SUMA.\u010cTVERC\u016e je efektivn\u00ed n\u00e1stroj v Microsoft Excel a Google Sheets, kter\u00fd umo\u017e\u0148uje vypo\u010d\u00edtat sou\u010det \u010dtverc\u016f zadan\u00fdch \u010d\u00edsel. Tato funkce je hojn\u011b vyu\u017e\u00edv\u00e1na v oblastech jako statistika a datov\u00e1 anal\u00fdza, a to pro \u00fa\u010dely jako jsou v\u00fdpo\u010dty variance a standardn\u00edch odchylek.<\/p>\n
