Answer 1

Answer:

This chapter outlines some basic issues in research design and analysis. It is included to inform the reader about the manner in which researchers have typically explored relationships among environmental, task, or psychological stressors and specific biomarkers or performance outcomes. Although this standard approach has been invaluable up to the present, continued reliance on this approach to the exclusion of more complex, nonlinear methods may impede progress toward developing predictors that are reliable across unique individuals, times, and circumstances. To start, a discussion of the research hypothesis and its relationship to the partitioning of variance is presented.
