In some investigations you may collect an awful lot of information. How can you use this raw data and make it meaningful? This section will help you to collect, organise and interpret the data efficiently.

Explaining your results

Imagine that you are asked to carry out a survey to find the number of pets owned by pupils in your school. You decide to ask 50 people, and record your results as follows:

0  2  1  2  0  4  1  0  2  2  1  6  1  1  2  8  0  12

2  1  2  0  3  2  0  1  3  0  1  4  0  3  0  2  3  6

3  3  0  1  2  0  1  1  3  0  2  0  3  2

You now have the information you need, but is this the most efficient way to collect and display the data?
