More than 50% of thispercentage scored above average.The major pitfall identified in this question is candidates‟ inability to recognise thatquestions C (i) & (ii) are examples of differences between probability and nonprobabilitysampling methods; thus, finding it difficult to list enough differences toearn them good mark.It is recommended that candidates make use of the study pack provided by theInstitute so as to be acquainted with the required techniques for the examination.INTERMEDIATE EXAMINATION - NOVEMBER 201098
