The third quartile (Q3) is the median of the upper half of the dataset. To find the third quartile in this dataset, we need to first arrange the numbers in ascending order:
45.5, 46.9, 47.2, 47.5, 48.1, 49.7, 52.1, 53.3
The upper half of the dataset is: 48.1, 49.7, 52.1, 53.3
The median of the upper half is the third quartile, so the answer is 50.9.
Therefore, the correct answer is: ○ 50.9
Identify the third quartile in the following dataset:
53.3, 46.9, 48.1, 49.7, 52.1, 47.5, 47.2, 45.5 (1 point)
○ 50.9
○ 53.3
○ 47.05
