  1. Note: ICC = intraclass correlation coefficient; WABA = within and between analysis **p < .01.
  2. aStudy 1: df(within) = 423 for individual referenced = 426 for group referenced; df(between) = 46.
  3. bStudy 2: df(within) = 133 for individual referenced =129 for group referenced; df(between) = 26.
  4. cE-test for parts significant at 30°.
  5. dA parts condition, in which ηw > ηb requires an inverse F-test (1/F) with df = N – J and J – 1 for the numerator and denominator respectively.
