Year 9
Lesson 5 Clean it up
In this lesson, learners will continue to develop their understanding of the investigative cycle by working through the data and analysis steps of the PPDAC cycle, using their own problem and the data that they are investigating. The lesson starts with a practical exercise that gives the learners some experience of data cleansing, to help them understand the problems that inaccurate data can pose for data analysis. The learners will then download the data they have collected and clean it before uploading it to CODAP, where they will analyse it further by creating visualisations. In this lesson, the learners will start to find some answers to the questions that they posed previously. It will also act as a platform for them to start drawing the conclusions they need to draw in the next and final lesson of the unit.
