Assessering

Leeruitkomste 5: Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak en om toevallige variasie te interpreteer en te bepaal.

Assesseringstandaard 5.1: Dit is duidelik wanneer die leerder vrae oor menseregte-, sosiale, politieke, kulturele, omgewing- en ekonomiese sake in eie omgewing stel;

Assesseringstandaard 5.2: Dit is duidelik wanneer die leerder geskikte bronne vir die versameling van data (insluitend maats, gesin en familie, koerante, boeke, tydskrifte) kies;

Assesseringstandaard 5.3: Dit is duidelik wanneer die leerder eenvoudige vraelyste (met ‘n verskeidenheid moontlike antwoorde) en ontwerp gebruik en vraelyste (met ja/nee-tipe-antwoorde) gebruik ten einde data te versamel (alleen en of as lid van ‘n groep of span) om vrae te beantwoord;

Assesseringstandaard 5.6: Dit is duidelik wanneer die leerder opsommings maak van ongegroepeerde numeriese data deur die gemiddeld, mediaan en modus as bepalers van sentrale neigings te bereken, en daartussen onderskei;

Assesseringstandaard 5.9: Dit is duidelik wanneer die leerder data wat op verskeie maniere voorgestel is krities lees en interpreteer ten einde gevolgtrekkings en voorspellings te maak wat sensitief is.
