Remember, KCC 0, indicates association, if the pvalue is small, we accept that KCC 0. The pvalue tells you the probability that some association was found purely by chance. This is saying that there is a % chance a nonzero KCC (some level of association) was found by chance alone. You decide based on the amount of risk you’re willing to take. A value like is typical. / 首先要看 p值，記住 KCC0，表示有聯(lián)系，如果p值很小，我們接受 KCC0。練習在 60s內完成 (3s/部件 ). 4. Each Appraiser will perform two trials 每個評價者重復 2次 5.
