1 is the anchor in the first problem and 2 is the anchor in the second problem. The average guess of the group given the first problem (with 1 as the anchor) is much lower than the group given the second problem (with 2 as the anchor). The average guess of the first group was 512 and the average guess of the second group was 2,250. Even though these answers were very different both were very far from the true answer, which was 40,320.
