1. Write the numbers:  
   $$85, \; 85, \; 81, \; 83, \; 98, \; 89, \; 90, \; 80, \; 95, \; 83$$

2. Calculate the sum of the numbers:  
   $$
   85 + 85 + 81 + 83 + 98 + 89 + 90 + 80 + 95 + 83 = 869
   $$

3. Count the number of values:  
   There are $$10$$ numbers.

4. Find the mean by dividing the sum by the number of values:  
   $$
   \text{Mean} = \frac{869}{10} = 86.9
   $$

Thus, the mean is $$86.9$$.
The mean is 86.9.
