West Gate Academy performed better. CA 1.1
Median:
West Gate’s median is higher than that of Brightmore West Gate Academy
High School; 60 > 55. / West Gate Akademie
OR
West Gate is much more negatively skewed; more One reason
students scored lower marks than median, but the referring to median /
majority of the students scored well (as indicated by the Een rede met
higher mean). verwysing na die
OR mediaan
Brightmore had a more balanced distribution, fewer
extremely low scores, but also a lower median. Reason referring to
IQR / Een rede met
IQR: verwysing na die IKW
Brightmore: IQR = 75 – 28 = 47
West Gate: IQR = 70 − 30 = 40
This indicates that West Gate has a more consistent
performance.
/
1.4 3 4
West Gate Akademie presteer beter.
Mediaan:
West Gate se mediaan is hoër as dié van Hoërskool
Brightmore; 60 > 55.
OF
West Gate is baie meer negatief skeef; meer studente
het laer punte as mediaan behaal, maar die
meerderheid van die studente het goed gevaar (soos
aangedui deur die hoër gemiddelde).
OF
Brightmore het ’n meer gebalanseerde verspreiding
gehad, minder uiters lae punte, maar ook ’n laer
mediaan.
IKW:
Brightmore: IKW = 75 – 28 = 47
West Gate: IKW = 70 − 30= 40
Dit dui daarop dat West Gate ’n meer konsekwente
prestasie het.
