Important Note
The marks allocated for each question do not necessarily reflect the number of words required to
answer the question. For example, some questions worth 2 or 3 marks can be answered in a few
words, though others might require one or two sentences. If you are struggling to stay within the
word count it is recommended that, if it is possible to answer a question in a few words, you do so in
order to save words for those questions that require more text to answer. For brief answers, the
following format is acceptable: Q. 5 (i): Random sampling.
