Erratum to Cousineau (2005):
Confidence intervals in within-subject designs:
A simpler solution to Loftus and Masson’s method
Three errors were found in Cousineau (2005), Table 2. Here, we present a corrected version of that table.
Three numbers were incorrectly entered in Table 2 from Cousineau (2005). Here we provide the corrected Table 2 (see Table 1 below). The remaining of the text follows without change.
D. Cousineau would like to thank R. Sekuler and H. F.
Volker for noting the errors in the original paper.
