Control Chart Project
This is a short assignment that asks students to find some data related to sustainability and determine whether the mean of that data set is statistically stable, and whether the process being measured is in control or out of control. It is often used for quality control in a production process, but in this activity, it is used to see if an ecosystem process is stable and healthy or disrupted (out of control.)
Statistics Learning Goals:
- Be able to construct an x-bar control chart for data from a time series.
- Be able to determine when the mean of a process is not statistically stable.
- Recognize that a similar process can be used to determine whether variation is not statistically stable.
Sustainability Learning Goals:
- Be able to find data relating to environmental sustainability.
- Understand whether certain parts of the environment are degrading and at risk.
