Statistical enquiry cycle

A cycle that is used to carry out a statistical investigation. The cycle consists of five stages: Problem, Plan, Data, Analysis, Conclusion. The cycle is sometimes abbreviated to the PPDAC cycle:

• The problem section is about formulating a statistical question, what data to collect, who to collect it from, and why it is important.
• The plan section is about how the data will be gathered.
• The data section is about how the data is managed and organised.
• The analysis section is about exploring and analysing the data, using a variety of data displays and numerical summaries, and reasoning with the data.
• The conclusion section is about answering the question in the problem section and giving reasons based on the analysis section.
