Question

Talia earned the following scores on her math tests: 82, 96, 100, 63, 91, 88, 82. What is the mean without the outlier? Round your answer to the nearest tenth.

Answer 1

To find the mean without the outlier, we need to calculate the mean without including the lowest score, which is 63.

Adding up the remaining scores:
82 + 96 + 100 + 91 + 88 + 82 = 539

There are now 6 scores to consider, so the mean is:
539 / 6 = 89.83

Rounded to the nearest tenth, the mean without the outlier is 89.8.
