​Understanding Statistical Process

​*Recognize statistical questions and anticipate variability in data related to the question.

*Describe the four stages of the statistical process.

*Discuss the different types of data that you can collect, display, and analyze.

​Objectives:

​Statistics is a problem-solving process because the heart of statistics is about determining a possible answer to a question that has variability.

​Formulating Statistical Questions

​The statistical process has four components:
STEP 1 Formulate a statistical question.
STEP 2 Collect appropriate data.
STEP 3 Analyze the data graphically and numerically.
STEP 4 Interpret the results of the analysis.

Statistical problem solving begins with a statistical question. A statistical question is a question that anticipates an answer based on data that vary.
