To find the range of the data set, we need to follow these steps:

1. **Identify the data set**: The percentages Ravi earned on his quizzes are:
   $$
   78, 80, 86, 82, 78, 67, 81
   $$

2. **Determine the maximum and minimum values**:
   - The maximum value in the data set is the highest percentage.
   - The minimum value in the data set is the lowest percentage.

3. **Calculate the range**: The range is calculated using the formula:
   $$
   \text{Range} = \text{Maximum} - \text{Minimum}
   $$

Now, let's find the maximum and minimum values from the data set:

- **Maximum**: $$86$$
- **Minimum**: $$67$$

Now, we can calculate the range:
$$
\text{Range} = 86 - 67
$$

Let's perform the calculation:
$$
\text{Range} = 19
$$

Thus, the range of the data set is $$19$$.
The range of the data set is 19.
