  • Materials Using a Normal Distribution
DATA-xls (updated) Assignments Statistics/Math Skills
U.S. Oil Consumption (10/11) pdf The excel file contains U.S. Oil extraction data and is set up to use solver (Excel 2007) or goal seek (older Excel) to do a normal model least squares curve fit. In the pdf file students do basic normal probability type questions about the U.S. oil model. The Excel sheet itself is interesting as it is set up to fit the data knowing only what Hubbert knew (I think) as long as all the current data. One can change the total oil extracted value to see how the peak and fit doesn't change much.
World Oil Consumption (10/11) pdf The excel file here is similar to the one above for the U.S. except that it contains world oil consumption.
  • Materials Using Linear Regression
DATA-xls (updated) Assignments Statistics/Math Skills
Global Temperature Anomalies, Relative to 1961-1990, 1850-present pdf This is a regression exercise to reproduce the graphic found here and used in many places.
Arctic Sea Ice Extent Data by Month (6/11) The excel file contains the average Arctic sea ice by month from 1978 to present. The reversion lines differ each month to the point where the winter months seem linear but the residuals for the summer months exhibit some curvature. In fact, 95% confidence intervals for slopes nearly separate (in fact they will depending on the latest update). The difference is at least partly due to a positive feedback loop due to changing albedo. The data is from the National Snow and Ice Data Center.
  • Materials Using T-tests and T-Intervals
DATA-xls (updated) Assignments/Information Statistics/Math Skills
Climate Simulation Data pdf The data in the file is available through NARCCAP (North American Regional Climate Change Assessment Programs. NARCCAP is an international program that serves the high resolution climate scenario needs of the United States, Canada, and northern Mexico, using regional climate model, coupled global climate model, and time-slice experiments. Right now I'm posting maximum temperature for various cities on the east coast (with the intention of expanding this). If you would like other cities or a different variable then send me an email and I'll try my best. Please read the corresponding Assignments/Information sheet so that you use the data properly. Currently it is best used for independent sample confidence intervals.
