Theo, Ara, Jose, and Dana all got 100 percent on their latest math test. Their scores on the previous six tests are listed. Whose mean test score will increase the most? (1 point)

O Ara: 100, 98, 99, 97, 100, 100
• Dana: 68, 74, 83, 80, 81, 82
• Theo: 84, 88, 81, 85, 77, 76
O Jose: 91, 93, 97, 96, 96, 96

1 answer

Ara's mean test score will increase the most. This is because her previous test scores are already high, so adding another perfect score will have a larger impact on her overall mean.
