The sum of the squared scores would be (Xi 2 = (10)2 + (12)2 + (13)2 = 100 + 144 + 169 = 413. Take careful note of the order of operations here. First, the scores are squared one at a time and then the squared scores are added. This is a completely different operation from squaring the sum of the scores: ((Xi)2 = (10 + 12 + 13)2 = (35)2 = 1225
