To find the median and mean number of hours watched by the students, we will follow these steps:

### Step 1: Calculate the Median
The median is the middle value when the numbers are arranged in ascending order.

1. **Arrange the data in ascending order:**
   $$ 9, 14, 18, 18, 18 $$

2. **Find the middle value:**
   Since there are 5 numbers (an odd count), the median is the third number in the ordered list.
   $$ \text{Median} = 18 $$

### Step 2: Calculate the Mean
The mean is calculated by summing all the values and dividing by the number of values.

1. **Sum the values:**
   $$ 9 + 14 + 18 + 18 + 18 = 77 $$

2. **Divide by the number of values (5):**
   $$ \text{Mean} = \frac{77}{5} = 15.4 $$

### Final Results
- **Median:** 18
- **Mean:** 15.4

Thus, the median number of hours is 18, and the mean number of hours is 15.4.
Median: 18 Mean: 15.4
