Column Variable

Each cell in the inner part of the table represents the count or percentage of a pairing, or cross-classifying, of categories from each variable. Sometimes additional rows and columns present the percentages of the overall total, the percentages of the row total, and the percentages of the column total for each row and column combination.

Two-way tables can reveal what combination of values is most prevalent in data. In the example, the tables reveal that bad wafers are much more likely to have particles than the good wafers. Because the number of good and bad wafers was unequal in this example, you can best see this pattern in the Row Percentage table. That table shows that nearly three-quarters of the wafers that had particles were bad, but only 20% of wafers that did not have particles were bad.
