Summary
| Description |
English: Q-Q plot for Washington State Route 20 (North Cascades Highway) first opening/final closing dates. Data are from fall 1972 through 2008. I ignored the winter of 1976-1977 when the highway did not close. A normal distribution would be a straight line in this plot. http://www.wsdot.wa.gov/Traffic/Passes/NorthCascades/closurehistory.htm |
