Statistical Investigations Part 1: Introduction to the PPDAC cycle
The lesson plans in this teaching unit were developed in conjunction with the TLRI research project: Building students’ inferential reasoning: statistics curriculum levels 5 and 6.
While each series of activities are set up as lesson plans, they may take more or less than a lesson of class time. They form a possible sequence of learning and each block works together with the other blocks. The lessons are developed using CensusAtSchool (2009) data, they could be adapted to any data set or any year of CensusAtSchool.
