The precise variables and units of measurement will be greatly dependent upon the area or the region of the study as well as the specific crop to be the focus of the study. For example, in the state of Wisconsin variability in the weather include the following: (1) Wetter winters/driers summers; (2) poor air quality; (3) more frequent floods, droughts, forest fires and storms with damage; and (4) increase in disease-carrying insect populations. (Wisconsin Natural Resources, 2007)
III. Specific Units of Analysis
Units of analysis within the scope of this type of study would necessarily be crop production units, which will be factored by temperature variances and rainfall variances as compared to the resulting production of crops within the area or region of the study. Other independent variables by which crop production might be factored include the factors of air quality, forest fires, storms and insect population in the area of the study. It is important...
