1. **State the problem:** Calculate the mean (average) of the values 8, 9, 7, 2, and 4.
2. **List the values:** The numbers are 8, 9, 7, 2, and 4.
3. **Sum the values:**
$$8 + 9 + 7 + 2 + 4 = 30$$
4. **Count the number of values:** There are 5 values.
5. **Calculate the mean:** The mean is the sum divided by the number of values.
$$\text{Mean} = \frac{30}{5} = 6$$
6. **Conclusion:** The mean of the numbers 8, 9, 7, 2, and 4 is 6.
