**Median, Mode, and Range** are measures of central tendency and dispersion in a dataset. Here's a detailed explanation of each:

1. **Median:**
   - The median is the middle value in a dataset when the numbers are arranged in ascending or descending order.
   - If the dataset has an odd number of observations, the median is the middle number.
   - If the dataset has an even number of observations, the median is the average of the two middle numbers.
   - **Example:**
     - Dataset: 3, 5, 7, 9, 11
     - Median: 7 (middle value)
     - Dataset: 3, 5, 7, 9, 11, 13
     - Median: (7 + 9) / 2 = 8

2. **Mode:**
   - The mode is the value that appears most frequently in a dataset.
   - A dataset can have more than one mode if multiple values appear with the same highest frequency.
   - If no number repeats, the dataset is said to have no mode.
   - **Example:**
     - Dataset: 3, 5, 7, 7, 9, 11
     - Mode: 7 (appears most frequently)
     - Dataset: 3, 5, 5, 7, 7, 9, 11
     - Mode: 5 and 7 (both appear most frequently)

3. **Range:**
   - The range is the difference between the highest and lowest values in a dataset.
   - It gives a measure of how spread out the values are.
   - **Example:**
     - Dataset: 3, 5, 7, 9, 11
     - Range: 11 - 3 = 8

**Example Dataset:**

Consider the dataset: 4, 8, 6, 5, 3, 9, 6, 2, 7

1. **Median:**
   - Arrange in order: 2, 3, 4, 5, 6, 6, 7, 8, 9
   - Median: 6 (middle value)

2. **Mode:**
   - Mode: 6 (appears twice, more frequently than any other number)

3. **Range:**
   - Highest value: 9
   - Lowest value: 2
   - Range: 9 - 2 = 7
