  1. What is statistics? “Statistics is the study of the collection, organization, analysis, and interpretation of data.”

  2. How tall are students in this class? How can we answer this question? What data would you need to collect?

  3. How tall are students in this class? Mean = 69.30 MEAN:

  4. How tall are students in this class? S = 4.84 STANDARD DEVIATION:

  5. Mean = 8.88 StdDev = 1.90 Mean = 9.02 StdDev = 3.77

  6. How tall are students in Michigan? How can we answer this question? Would you need a different sample compared to our previous question?

  7. How tall are students in Michigan? SE = 0.80 STANDARD ERROR:

  8. Are students in Michigan taller than students in Ohio?

  9. SQUARED! Half the class gets bean type 1, half the class bean type 2 Do the two types of beans have different lengths?

  10. MEAN: STANDARD DEVIATION: STANDARD ERROR:
