NTSANGANI SUBJECT: ERRATA – MATHEMATICS P2 GRADE 12 PREPARATORY EXAMS DATE: 15 SEPTEMBER 2022 Mathematics P2 was written on Monday, 12 September 2022. We were made aware of certain errors, amendments and omissions that were discovered during the marking process. In order to address this and to ensure that the learners are not disadvantaged, the following standardised approach to marking must be adopted across the Province. The following guidelines with regard to marking was prepared in conjunction with the examiner and moderator. ERRATA: MATHEMATICS P2 (MARKING GUIDELINE) 1.2 Anchor point must be (420 ; 0) Upper Limit – 780 Last point has 𝑦 − 𝑐𝑜𝑜𝑟𝑑𝑖𝑛𝑎𝑡𝑒 𝑜𝑓 100 1.3 Mark according to learner’s Ogive. 1.4 Please accept between 42% - 44%. Marking must be according to the learner’s response on their drawing of the Ogive. 2.1 No penalty for rounding. 2.2 No penalty for rounding. 2.3 Accept if learner states that 5,4 is within the domain of the data set. Or if learner mentions that it is valid as the correlation coefficient is 0,92. 2.4.1 Accept if learner merely states that the mean will change.
