° Live experimentation shows a significant difference in the information and knowledge gathered. ° Live experimentation can be concluded to have significant value and insight. ° The difference between Less Info and More Info without any hands-on experimentation is only limited. In other words, having additional information on paper, without the ability to perform hands-on experimentation, yields little difference and only minor benefits.

Predictability Without Experimentation Is Very Limited The research question we are attempting to answer in this section is: • Can the final outcome of a detailed experiment be predicted by performing some basic Pre-experimental survey? If the research question above is found to be predictable, this would save the DoD considerable time and expense. Results from detailed experimentation can be predicted from basic preliminary review of the technology. Table 15 shows a sampling of the results from a multivariate regression model. Little to no statistical significance is discernible when using Pre experimental data to predict the outcomes of the Post-experiment scores.
