What is the difference between statistical questions and mathematical questions?
Mathematical questions are asking you to find an answer/number. Finding the statistic is a mathematical problem.
Statistical questions are asking to analyze those answers/number. Statistics is interpreting the data.
How to formulate an appropriate statistical question
- Consider what the data is
- where you are getting the data
- formulate a question that is free of bias
