How is stats different than mathematics?

Stats concentrate on the context of the numbers.  The analysis

Mathematics is how you get the numbers/data

What questions would you ask if you were teaching a lesson on mean?

Mathematical   Find the mean of the class spelling scores.

Statistical - What do these scores/mean tell me?

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
• Look at the research, make sure it is valid research

Key with Data Analysis - you don't do the analysis until you do the math.  The math comes first, the analysis comes next.
