WebType of variables: categorical. Sample size: 253. Program used: SPSS version 21. Problem: in several ways the assumption for a chi-square test is not met. Under some tables it is written (e.g.): 4 cells (22.2%) have expected count less than 5. The minimum expected count is 1.85 or 7 cells (50.0%) have expected count less than 5. WebIt is typically used as an alternative to the Chi-Squared Test (2x2 table) when cell counts are small. Interpretation When the (two-sided) P-value (the probability of obtaining the observed result or a more extreme result) is less than the conventional 0.05, the conclusion is that there is a significant relationship between the two ... WebThe usual rule of thumb is that all cell counts should be at least 5, though this may be a little too stringent. When some cell counts are too small, you can use Fisher's exact test which is also provided by the CHISQ option. The Fisher test, while more conservative, also shows a significant difference between the proportions (p=0.0405). dewalt lowes deal
