Prior knowledge • •
Know and understand the terms primary data, secondary data, discrete data and continuous data. Students may well have studied some or all of these terms before in GCSE Mathematics or GCSE Statistics, but full explanations are given in the Student Book to ensure all students have full access to the work.
Learning objectives • •
Identify qualitative, quantitative, primary and secondary data. Identify discrete and continuous data, independent and dependent variables.
Key terms and definitions • • • • • •
Continuous data: data that is measured. Discrete data: data that is counted. Primary data: data that comes directly from first-hand experience. Qualitative data: non-numerical data that describes a quality. Quantitative data: numerical data. Secondary data: data that already exists or has been processed.
Common misconceptions •
Confusing the words ‘qualitative’ and ‘quantitative’. Remind students that quantities are measured, so they require the use of numbers, and that the word ‘quantitative’ starts the same way as ‘quantities’.
