To find the first quartile, we first need to arrange the dataset in ascending order:
17, 18, 20, 34, 42, 47, 54, 56, 62, 67, 82
Since there are 11 numbers in the dataset, the first quartile is located at position (11+1)/4 = 3rd position.
The number at the 3rd position is 20.
Therefore, the first quartile is 20.
given the following dataset what is the first quartile round to the nearest tenth, if necessary
42 82 67 34 54 62 17 47 56 18 20
