Identify the first quartile in the following dataset:

5,7,9,4,3,2,1,0,11,12,6,3,4,3,2,6

1 answer

The dataset needs to be arranged in ascending order first:

0, 1, 2, 2, 3, 3, 3, 4, 4, 5, 6, 6, 7, 9, 11, 12

The first quartile (Q1) is the middle number between the smallest number and the median. In this case, the smallest number is 0, and the median is the middle number between 3 and 4, which is also 3. So, the first quartile in this dataset is 3.
