Document Summary
Chapter 29 introduction to statistics and sampling. 10/04/18: statistic a numerical value of a quantity used to describe data. Sometimes we use the word statistics to describe the study and processes of collecting, organizing, and analyzing data: a principal is interested in knowing whether or not a school"s discipline standards are fair. The principal gets a limited pool of people who are also likely biased: an animal shelter wants to know how the public feels about animal adoption fees. They send out a survey to people on the mailing list that have adopted previously. You lose the opinion of the people you more want to hear from, those who have not adopted, due to high adoption fees or otherwise: the democratic party wants to know how he americans feel about illegal immigration. They send out surveys to everyone on their mailing list.
