Identify the third quartile in the following dataset: 53.3, 46.9, 48.1, 49.7, 52.1, 47.5, 47.2, 45.5 Responses 50.9 50.9 47.05 47.05 53.3 53.3 47.8

Answer 1

To identify the third quartile in the dataset, you first need to arrange the numbers in ascending order:

45.5, 46.9, 47.2, 47.5, 47.8, 48.1, 49.7, 50.9, 50.9, 52.1, 53.3, 53.3

The dataset has 12 numbers, so the third quartile is located at the 3/4 * n = 3/4 * 12 = 9th position.

The number at the 9th position is 50.9, so the third quartile in the dataset is 50.9.
