The Systems Are Independent and Uncorrelated The research question we are attempting to answer in this section is: • Are the three systems somehow correlated in terms of their value to the warfighter? Table 12 shows a sampling of the results from the linear and nonlinear correlation matrices.

We conclude that: • It seems that very little correlation exists among the three final scores of the systems. The results and conclusion make sense, as there should be very little rela tionship among the Direct-Control, Remote-Control, and Autonomous systems, especially when they are tested independently and at different times. Each Level of Experimentation Yields Valuable Actionable Intelligence The research questions we are attempting to answer in this section are: • Within each experimentation stage, are the three systems perceived to be different (Direct-Control vs. Remote-Control, Direct-Control vs. Autonomous, and Remote-Control vs. Autonomous systems)?
