To find the first quartile, we first need to arrange the data in ascending order:
0, 1, 2, 2, 3, 3, 3, 4, 4, 5, 6, 6, 7, 9, 11, 12
Since there are 16 data points, the first quartile is located at the position (16+1)/4 = 4.25. This position falls between the 4th and 5th data point.
Calculating the average of the 4th and 5th data points:
(3 + 3) / 2 = 6.5
Therefore, the first quartile (Q1) in this dataset is 6.5.
dentify the first quartile in the following dataset: 5, 7, 9, 4, 3, 2, 1, 0, 11, 12, 6, 3, 4, 3, 2, 6 Responses 4 4 6.5 6.5 0 0 2.5
