Question

Mean and mode quick check

Answer 1

Certainly! Here’s a quick check on how to find the mean and mode of a set of numbers.

### Mean
The **mean** (average) is calculated by adding all the numbers together and then dividing by the count of the numbers.

**Formula**:
\[ \text{Mean} = \frac{\text{Sum of all values}}{\text{Number of values}} \]

**Example**:
For the numbers 2, 3, 5, 7, and 10:
- Sum = 2 + 3 + 5 + 7 + 10 = 27
- Number of values = 5
- Mean = 27 / 5 = 5.4

### Mode
The **mode** is the number that appears most frequently in a set of numbers. A set of numbers may have one mode, more than one mode, or no mode at all.

**Example**:
For the numbers 1, 2, 2, 3, 4:
- The mode is **2** (since it appears most frequently).

For the numbers 1, 1, 2, 2, 3:
- The modes are **1** and **2** (it's bimodal).

For the numbers 1, 2, 3:
- There is no mode (each number appears only once).
