There are 5 questions in this section. Complete each question and then pass your answers to your tutor for marking.
For each question decide which of the types of graph from Section 1 is the most appropriate and draw it. If you are using squared paper, then obviously two-dimensional illustrations will be all you can manage; if you and your tutor decide that you can do the graphs on a computer, perhaps you can be a bit more adventurous!
Where you think there is more than one way to illustrate the data, or where the same method seems to lend itself to two questions, draw one type of graph for one question, and another for another question, to give yourself practice.
