Calculate the value by following steps:
- step0: Calculate:
  $$20-10$$
- step1: Subtract the numbers:
  $$10$$
Let's solve the problems step by step.

### Problem 6: Mode Change After Adding 18

1. **Current Data Set**: $$ 20, 14, 10, 15, 15, 14, 19, 15 $$
2. **Identify the Mode**: The mode is the number that appears most frequently in a data set.
   - In the current data set, the number $$ 15 $$ appears three times, while $$ 14 $$ appears twice, and all other numbers appear once. Thus, the mode is $$ 15 $$.

3. **Add the Value 18**: Now the data set becomes $$ 20, 14, 10, 15, 15, 14, 19, 15, 18 $$.

4. **Identify the New Mode**: 
   - In the new data set, $$ 15 $$ still appears three times, while $$ 14 $$ appears twice, and $$ 18 $$ appears once. Therefore, the mode remains $$ 15 $$.

### Conclusion for Problem 6:
- **Mode Change**: There is **no change** in the mode after adding the value $$ 18 $$.

### Problem 9: Find the Range

1. **Current Data Set**: $$ 20, 14, 10, 15, 15, 14, 19, 15 $$
2. **Calculate the Range**: The range is calculated as the difference between the maximum and minimum values in the data set.
   - Maximum value: $$ 20 $$
   - Minimum value: $$ 10 $$

3. **Calculate the Range**:
   $$
   \text{Range} = \text{Maximum} - \text{Minimum} = 20 - 10 = 10
   $$

### Conclusion for Problem 9:
- **Range**: The range of the data set is $$ 10 $$.

In summary:
- The mode does not change after adding $$ 18 $$.
- The range of the data set is $$ 10 $$.
- The mode remains the same after adding 18. - The range of the data set is 10.

6.) How does the mode change after adding the value " 18 " to the data set? Increase, decrease, or no change? \( 20,14,10,15,15,14,19,15 \) 9.) Find the range.
