To calculate the average arithmetic mean of a set of numbers, you need to follow a simple formula:
- Add all the numbers together.
- Divide the sum by the total number of values.
Let’s break it down with your given numbers: 8, 7, 7, 5, 3, 2, and 2.
1. **Calculate the sum**:
8 + 7 + 7 + 5 + 3 + 2 + 2 = 34
2. **Count the total number of values**:
There are 7 numbers in total.
3. **Divide the sum by the total number of values**:
Average = Sum / Count = 34 / 7 ≈ 4.857
Thus, the average arithmetic mean of the numbers 8, 7, 7, 5, 3, 2, and 2 is approximately 4.86 when rounded to two decimal places.
