To find the interquartile range, we first need to find the 1st quartile (Q1) and the 3rd quartile (Q3).
First, let's sort the dataset in ascending order:
35.6, 38.1, 41.0, 43.0, 44.2, 44.4
The median of the dataset is the average of the middle two numbers:
(41.0 + 43.0) / 2 = 42.0
Now, let's find Q1. Q1 is the median of the lower half of the dataset. In this case, the lower half is:
35.6, 38.1, 41.0
Therefore, Q1 = 38.1
Next, let's find Q3. Q3 is the median of the upper half of the dataset. In this case, the upper half is:
43.0, 44.2, 44.4
Therefore, Q3 = 44.2
Now, we can calculate the interquartile range (IQR) as:
IQR = Q3 - Q1
IQR = 44.2 - 38.1
IQR = 6.1
Therefore, the interquartile range of the dataset is 6.1.
