Define mean, median and mode with Example

**Definitions:**

1. **Mean:** The mean is the average of a set of numbers. It is calculated by adding all the values together and dividing by the number of values.
   - **Example:** For the numbers 2, 4, 6, and 8:
     \[
     \text{Mean} = \frac{2 + 4 + 6 + 8}{4} = \frac{20}{4} = 5
     \]

2. **Median:** The median is the middle value in an ordered set of numbers. If the number of values is odd, it’s the middle number; if even, it’s the average of the two middle numbers.
   - **Example (Odd Set):** For the numbers 1, 3, and 5, the median is 3.
   - **Example (Even Set):** For the numbers 2, 4, 6, and 8, the median is \(\frac{4 + 6}{2} = 5\).

3. **Mode:** The mode is the number that appears most frequently in a set of numbers. A set may have one mode, more than one mode, or no mode if all numbers appear equally.
   - **Example:** For the numbers 1, 2, 2, 3, and 4, the mode is 2, as it appears most frequently.
