The sum of set of measurements divided by the number of measurements in the set

The sum of a set of measurements divided by the number of measurements in the set is the **mean** or **average** of the set. Mathematically, it is expressed as:

\[
\text{Mean} = \frac{\sum_{i=1}^{n} x_i}{n}
\]

Where:
- \(x_i\) are the individual measurements in the set,
- \(n\) is the total number of measurements,
- \(\sum_{i=1}^{n} x_i\) represents the sum of all the measurements.

Here are 5 related questions to expand on this topic:
1. How is the median different from the mean?
2. What is the relationship between the mean and variance?
3. How do outliers affect the mean of a dataset?
4. Can you explain the difference between the arithmetic mean and geometric mean?
5. What is the weighted mean, and how is it calculated?

**Tip**: The mean is highly sensitive to extreme values (outliers), which can significantly skew the result.

Understand how to calculate the mean (average) of a set of measurements by dividing the sum of all values by the number of measurements. This explanation covers key statistical concepts and is suitable for students in Grades 6-8.
