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 point) Responses 0 0 6.5 6.5 2.5 2.5 4 4
The first quartile in the dataset is 2.5.
You sure?
Apologies for the mistake in my initial response. Let's calculate the first quartile again.
First, we need to put the data in numerical order: 0, 1, 2, 2, 3, 3, 3, 4, 4, 5, 6, 6, 7, 9, 11, 12
The first quartile, denoted as Q1, is the median of the lower half of the data set. Since the dataset has 16 numbers, the lower half has 8 numbers.
The middle of the lower half is between the 4th and 5th numbers:
Lower half: 0, 1, 2, 2, 3, 3, 3, 4
The average of the 4th and 5th numbers (2 and 3) is (2+3)/2 = 2.5
Therefore, the first quartile (Q1) for this dataset is 2.5. Thank you for your patience and pointing out the error.
