This learning video addresses a particular problem of selection bias, a statistical bias in which there is an error in choosing the individuals or groups to make broader inferences. Rather than delve into this broad topic via formal statistics, we investigate how it may appear in our everyday lives, sometimes distorting our perceptions of people, places and events, unless we are careful. When people are picked at random from two groups of different sizes, most of those selected usually come from the bigger group. That means we will hear more about the experience of the bigger group than that of the smaller one. This isn't always a bad thing, but it isn't always a good thing either. Because big groups ''speak louder,'' we have to be careful when we write mathematical formulas about what happened in the two groups. We think about this issue in this video, with examples that involve theaters, buses, and lemons. The prerequisite for this video lesson is a familiarity with algebra. It will take about one hour to complete, and the only materials needed are a blackboard and chalk.

1) What are some of the biological effects of dam removal (good and bad)?
2) What are some of the more pressing/compelling reasons to remove a dam? Explain.
3) The Stanley and Doyle (2003) article states that, "dam removal cannot be avoided." Hypothetically, let's say you are placed on a committee to oversee the removal of the Aswan High Dam, since Doyle et al. (2003) states that, "the functional lifespan of most dams is approximately 60-120 years." What scientific studies would you conduct before/during/after dam removal? Why?

This activity uses an assortment of digital resources relevant to exploring resource development on Native American lands. The activity is based on a website that uses an Earth System approach to help students understand how Native American lands have been impacted by resource development. Students are assigned to investigate different aspects of the same problem or issue. For example, each team might analyze a different but related data set or read an article on different aspects or viewpoints on the same topic. Once each team member thoroughly understands his/her team's aspect of the problem, new groups are formed, with at least one representative from each original team. Each individual then explains her/his team's aspect of the problem to the new group. In this way, every student learns different aspects of the problem. Each group then uses combined information to create a complete summary of the issue. The jigsaw technique is based on work published by Barbara Tewksbury [Tewksbury, 1995] .
