Wind Energy & Climate Change

 
METHODOLOGY
Five hundred and nine telephone interviews were started June 14th and completed June 23rd.  These interviews were completed during the hours of 5:30PM and 10:30PM Central Standard Time and were conducted over seven days using Random B sampling technique. Interviews were conducted in the following 14 states: Colorado, Iowa, Illinois, Indiana, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, Ohio, South Dakota, Texas, and Wisconsin. These 14 states represent  88% of total U.S. planted corn acreage in 2001 based on the June 29, 2001 USDA-NASS Acreage report.
RMA obtained listed sample of corn producers in the 14 specified states which was used for this study.  It was comprised of individuals that have a minimum of 100 acres of corn planted.  Respondents at the beginning of the study were asked how many acres of corn they have planted, anyone below the 100 acre requirement was then terminated.
When the study was completed, results were cross-tabulated and analyzed.  The sampling margin of error plus or minus 4.5 percentage points at a 95% confidence level for the overall study.  The margin of error will increase if each state is analyzed individually. Differences in the total sample answers of more than eight percentage points should be considered statistically significant. Differences in the total sample of five to nine percentage points should be considered directional rather than statistically significant.
