Question

Determine the minimum, maximum, and quartile values. Remember, the first step is to put the values in order from least to greatest.

{2.25,1.25,3.75,3.5,2.5,4,3,2,1.75}

Answer 1

To find the minimum, maximum, and quartile values, arrange the data in order and identify the corresponding values. The minimum value is 1.25, the first quartile is 2, the median is 2.5, the third quartile is 3.75, and the maximum value is 4. The width of the interquartile range (IQR) is 1.75.

Step-by-step explanation:

The given data set is: 2.25, 1.25, 3.75, 3.5, 2.5, 4, 3, 2, 1.75.

To find the minimum, maximum, and quartile values, we first need to arrange the data in order from least to greatest:

1. 1.25
2. 1.75
3. 2
4. 2.25
5. 2.5
6. 3
7. 3.5
8. 3.75
9. 4

The minimum value is 1.25, the first quartile is 2, the median is 2.5, the third quartile is 3.75, and the maximum value is 4.

Additionally, the width of the interquartile range (IQR) can be calculated by subtracting the first quartile from the third quartile: 3.75 - 2 = 1.75.
