Collecting, sampling & presenting data
Narrated lesson · press play
In Paper 3 you become a real investigator, and this lesson gives you the whole toolkit. We learn the five ways to collect data — questionnaires, interviews, observation, measurement and documents — and weigh up the advantages and disadvantages of each. We meet the pilot study (a small trial run before the real thing), the difference between a population and a sample, and three fair sampling methods: random, stratified and systematic. Finally we present findings in bar graphs, pie charts, line graphs and sketch maps, and learn to draw sensible conclusions and recommendations — all in a Namibian setting.
