| Abstract: | Abstract: The paper conducted a experiment to investigate weather causal judgment ovaries with sample size, and compare the predictions of five models, ΔP、Power-PC、SS、Support and χ2. Contingency were presented with table format, results show that:（a）The Sample size factor have different effect on different contingency : High sample lead to the low estimate in ΔP = 0 , have no effect in 0< |ΔP | = Power-PC , while lead to high estimate in |ΔP|
