    A description of the standard error of estimate is given in appendix A under "Methodology of Survey." The percentage (or relative)
standard errors in this table may be converted to standard errors of estimate by multiplying the percentage shown by the associated
estimate. For example, the relative standard error of estimate for R&D performance for all company size groups in the food and
kindred products industry (SIC 20) is shown as 1 percent, and the associated total R&D estimate for this industry is shown
as $294 million dollars in the table entitled, "Funds for R&D Performance by Industry and Selected Company Size
Groups: 1974." The standard error of estimate, then, is .01 times 294, or 2.94.

     Less than 0.5 percent.
