V = 0 can be interpreted as independence (since V = 0 if and only if χ2 = 0). To make a test we prepare a contingency table end to calculate f e (expected frequency) for each cell of the contingency table and then compute χ 2 by using formula: Null hypothesis: χ 2 is calculated with an assumption that the two attributes are independent of each other, i. These sample tables are also available as a downloadable Word file (DOCX, 37KB).
