A typical five-way fully factorial design applied to a reasonably large sample of random data has about an 80% chance of producing at least one significant effect by conventional F tests at the .05 critical level (Hurlburt & Spiegel, 1976). 5, 116127. Snyder, (1998). Rubin, The essence of the RCM is to formulate causal questions in this way and to use formal statistical methods to draw probabilistic causal inferences, whether based on Fisherian randomization-based (permutation) distributions, Neymanian repeated-sampling randomization-based distributions, frequentist superpopulation sampling distributions, or Bayesian posterior distributions (Rubin, 1990a).
