A worksheet (pdf/docx) on collecting data where students match types of data to keywords such as primary, secondary, qualitative, quantitative, discrete and continuous.
A Match-up activity (pdf/docx) on sampling methods, where students match the method with its description and some advantages and disadvantages of the technique. Includes an answer sheet.
A worksheet (pdf/docx) about surveys showing 7 different survey questions. Students are asked for one criticism of each question and to rewrite it in a more suitable form.
A worksheet (pdf/docx) about representing data containing 5 questions. Each question has a table containing data and students are asked to draw 2 bar charts, a pie chart, a line graph and a scatter graph. This is a good revision exercise to remind students of the variety of graphs they already know how to draw.
