Question

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

Answer 1

You sure?

Answer 2

The first quartile in the dataset is 2.5.

Answer 3

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.
