1. Minimum value: The smallest data point in the dataset.
2. Lower quartile (Q1): The value below which 25% of the data falls.
3. Median: The middle value of the dataset.
4. Upper quartile (Q3): The value below which 75% of the data falls.
5. Maximum value: The largest data point in the dataset.
6. Interquartile range (IQR): The range of values between the lower and upper quartiles.
7. Outliers: Data points that fall outside the range of the whiskers.
Display the following dataset as a box plot: 18, 20, 22, 24, 26, 28, 30.
To create a box plot for the dataset 18, 20, 22, 24, 26, 28, 30, we first need to find the minimum, maximum, median, lower quartile (Q1), and upper quartile (Q3) values:

Sorted dataset: 18, 20, 22, 24, 26, 28, 30
Minimum value: 18
Lower quartile (Q1): 21 (the average of the values 20 and 22)
Median: 24
Upper quartile (Q3): 28

Now we can create the box plot:

```
| +--------*--------+ |
Lower whisker Lower box Upper box Upper whisker
(Min) (Q1) (Q3) (Max)
```

This box plot visually represents the dataset 18, 20, 22, 24, 26, 28, 30, showing the minimum value (18), lower quartile (21), median (24), upper quartile (28), and maximum value (30).
