Simple Data Analysis

This website is designed to provide an initial, simple analysis of a string of data for a set of years to determine whether a policy (or other influential) change at some point in time caused a change in that indicator.  The program provides:
  • a graph of the data, 
  • a list of the data you entered, and
  • summary statistics.
These are designed to help you determine what impact, if any, the policy change had on the data of interest. 

For example, you could put in CFC emissions from 1979 to 1997 to see if the Montreal Protocol to Protect the Ozone Layer signed in 1987 actually led to any reduction in CFC emissions. 
Example output for the Montreal Protocol.

I would appreciate any feedback you might care to give me on how this program can be improved - rmitchel@uoregon.edu. 

To begin the process of entering data, enter your name and the first and last years of the data you will be entering.  This will set up the data entry form.
