21 Fill in the Blank 0.75 points In evaluating the possibility of a functional relation (V. Experimental Control/Internal Validity) we look for the immediacy and magnitude of change in the DV when the intervention is implemented. The DV in Yang et al. (2025) revealed an immediate effect between the last session of baseline (not schedule probe) and the first session of intervention (without any overlap). All three participants correctly completed 0% of the self-checkout steps on the last baseline session. What was the data value for the first session of intervention for each of the participants? Type a double-digit numeral for each of the following. . You do not need to type the % symbol-it is already there.

Edit View Insert Format Tools Table 12pt w Paragraph V EVEY There are three demonstrations of effect shown in the graphs, one for each participant (Ling, Feng, and Zheng). Each participant shows a clear increase in independent correct responses when the intervention is introduced, following a low baseline, thus replicating the treatment effect across three subjects. D
