Document Summary
Unobserved population problem is a methodology specifically studied in selection bias. They have a lot to choose from, but few are published. These were published due to political criteria/newsworthiness, that is what we need to find. Large sample comparison, because there is many for a week available what is actually published to approximate unobserved population. Subjectivity: tend to manifest more when you try to find presentation bias. Partisan bias: news is politically motivated to support one side of a political conflict than another thereby advantaging that side. Selection bias: select news that are not newsworthy rather select from the agenda. Presentation bias: once hypothetically publish stories that are newsworthy the way they talk about story distorts the reality. Us, own subjectivity as people, we think the news is bias (95%) whether it is or not, it is the subjectivity problem. You see presentation bias where it doesn"t exist. Media bias say more about us than the media coverage.
