Document Summary

Concepts and modes of reasoning are major intellectual accomplishments. Understanding of natural and social systems and processes based largely on numerical evidence. To help you survive in the 21st century. Statistical reasoning may be as necessary as citizenship. Examples: calculate the average age based on data for all 150 students in the course. You have just calculated a parameter based on the the population data. 19. 8 years of age: calculate the average age for a subset of these students. You have calculated a statistic based on a subset of the population, 20. 1 years of age: calculate the average age of a randomly chosen subset, use this value to estimate the average age of the entire class. This is an estimate of a parameter because what you are estimating deals with the entire class. Examples: y = 3 x 6 + 12 / 22. Addition: 18+3= 21, therefore y=21: y = (4+6) / 2 + 53 5 x 3.
