Use of data
Read the notes, then try the questions. Each one is marked the moment you press Check, and shows the right answer and why.
Key ideas
- Mean = add all the scores, then divide by how many scores there are.
- Percentage change = change divided by the original value, times 100. For example, 50 to 60 is (10 divided by 50) x 100 = 20%.
- A trend is the direction results move over time. A prediction from a trend is an estimate, not a certainty.
- Choose a bar chart to compare groups. Choose a line graph to show change over time.
- Quantitative data is numbers. Qualitative data is descriptions. Calculators are allowed in both papers.

Exam tip
Show your working in 'calculate' questions, because a method mark can be earned even if the final answer is wrong. For a graph question, say what the numbers do (rise, fall, level) and quote at least one value.
