To create a box plot for the dataset \(23, 24, 25, 26, 27, 28\), we need to identify the following five key values:
- Minimum: The smallest number in the dataset.
- First Quartile (Q1): The median of the first half of the dataset.
- Median (Q2): The middle number of the dataset.
- Third Quartile (Q3): The median of the second half of the dataset.
- Maximum: The largest number in the dataset.
Let's calculate these values:
- Minimum: \(23\)
- Maximum: \(28\)
- Median (Q2): Since there are six values in the dataset, the median is the average of the 3rd and 4th values: \[ Q2 = \frac{25 + 26}{2} = 25.5 \]
- First Quartile (Q1): This is the median of the first half of the dataset (\(23, 24, 25\)): \[ Q1 = 24 \]
- Third Quartile (Q3): This is the median of the second half of the dataset (\(26, 27, 28\)): \[ Q3 = 27 \]
Now we have all the necessary values to complete the box plot:
- Minimum: 23
- Q1: 24
- Median (Q2): 25.5
- Q3: 27
- Maximum: 28
These five values will be used to construct the box plot.
