Beyond the Answer

Om die derde kwartiel (Q3) van die gegewe data te bereken, volg ons die stappe van sortering en kwartielberekening. Die data is reeds gesorteer: \[ 30, 32, 33, 34, 37, 39, 39, 44, 48, 51, 51, 52, 52, 52, 53, 55, 57, 59, 97, 99 \] Daar is 20 waarnemings in totaal. Q3 kan bereken word deur die posisie van die derde kwartiel te vind. Hierdie posisie is: \[ Q3 = \frac{3(n + 1)}{4} = \frac{3(20 + 1)}{4} = \frac{63}{4} = 15.75 \] Die posisie van Q3 is dus tussen die 15de en 16de waarneming. Die 15de en 16de waardes in die gesorteerde lys is 53 en 55. Bereken Q3: \[ Q3 = \frac{53 + 55}{2} = 54 \] Die derde kwartiel (Q3) is dus 54.
