How Ranking Questions Work

The average rank of an item in a ranking question is calculated based on its weight and the number of responses in which the item has the same rank.

An item’s average weight is calculated using the formula: w1p1 + w2p2 + w3p3 + w4p4 / total number of responses, where “w” is the weight of a rank and “p” is the number of responses in which the item has the same rank. The item with the highest average weight has the highest average rank. The items with lower average weights have gradually lower ranks.

Note
Note When you add items to a ranking question, a weight is automatically applied to each item. When you customize the weight of a ranking item, make sure that the highest rank has the highest weight, and the lower ranks have lower weights. For example, if you have four ranking items, the values look like this.

1 4
2 3
3 2
4 1
