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|

Key words: Key words: causal inference, sample size, Support-model, SS-model.

摘要: 摘 要:使用纸笔测验探讨表格集中呈现信息条件下取样大小对单一因果关系强度推理的影响,并比较五种模型ΔP、效力PC、SS效力、Support和χ2的预测与实验数据的相关。结果显示:(1)取样大小对不同的问题有不同的影响:高取样在ΔP=0时导致了低估计值,在0<|ΔP|=PPC时没有效果,在|ΔP|
