Aberration • “What a statistical aberration!” remarks university don X. N. Iraki on the recently released KCSE exam results. He adds: “It’s statistically impossible for a school’s mean score to rise from 6.2 to 10.26 or from 5.21 to 9.28 in six months. Anybody who has ever taught can attest to that. Such a statistical aberration needs an explanation. Over to the Education ministry.” His contact is [email protected].
