Calculation Solution
Mean = 30.0000
Count: 5, Sum: 150
Mathematical Formula
Mean = Sum of Values / Number of Values
Overview & Explanation
The arithmetic mean (average) is calculated by adding all numbers in a dataset and dividing by the total count of numbers.
How It Works
- Sum all numbers in the dataset.
- Count total numbers in the list.
- Divide sum by count.
Practical Applications
- Calculating test grade averages.
- Determining average monthly expenses.
Worked Example: Average of 10, 20, 30, 40, 50
Find the mean.
1
Sum of Values
10 + 20 + 30 + 40 + 50
= 150
2
Divide by Count (5)
150 / 5
= 30
