We examined how to select the method of statistical significance test as to the evaluation obtained by diagnostic imaging.We used 6-10 pairs of small data, and classified the distribution style using skewness and kurtosis.In statistical significance test, we used the paired t-test as a parametric test, and the Wilcoxon test as a non-parametric test.We tried to select the method of the statistical significance test in consideration of the power of test in each distribution style.The result of the X^2test, Which is a test of normalization, there was no significance.In the case the paired t-test may be adecuate, considering the power of test, we should use the Wilcoxon test, incase that the both bottoms spread or the right bottom spreads.
