From page 268...
... It is thus appropriate to cast any comparison between funding levels in different eras in a likelihood framework. The specific question addressed in this appendix is: How likely is it that the level of water resources research funding in the late 1990s is greater or less than the analogous level of the mid 1970s?
From page 269...
... If the zero-level cumulative probability value mentioned above is near 50 percent (say within 10 percent up or down) , then it is doubtful that differences in funding levels are significant.

... This makes zero the median and mean of the distribution of differences. FIGURE C-1 Cumulative frequency distributions of 10,000 samples of generated differences between means of years 1973, 1974, 1975 and of years 1999, 2000, 2001 for total water resources research (WRR)
