Why do we collect, display and analyse data?
Collect data: gathering and counting, taking surveys, giving out questionnaires or by taking measurements
Display and analyse data 🡪 describe the things, both physical and social, that we see and experience around us. We can:
find answers to questions that might not be immediately obvious
identify questions for further investigation.
To better understand and evaluate the large amounts of statistical information that we meetdaily, as seen in the media: sports news, product advertisements, weather updates, health and environmental reports, service information, political campaigning, stock market reports and forecasts, and so on.
Through activities that involve data handling, we naturally begin to formulate questions. This is a valuable skill that helps us to make informed decisions.
We also acquire skills that enable us to recognise some of the inaccurate ways in which data can be represented and analysed, and to develop the ability to evaluate the validity of someone else’s research.
