Formula & How It Works
Arithmetic Mean Formula
The arithmetic mean is computed by summing all values in the dataset and dividing by the total count of values.
Worked Examples
Test Scores Average
Input: 85, 90, 78, 92, 88
Explanation: Summing 85+90+78+92+88 = 433. 433 / 5 = 86.6.
Dataset with Repeating Numbers
Input: 10, 20, 20, 40
Explanation: Sum is 90 / 4 = 22.5. The number 20 appears most frequently.
Frequently Asked Questions
What is the difference between mean and median?▼
The mean is the arithmetic average of all numbers, while the median is the middle value when all numbers are sorted in order.
When should I use median instead of mean?▼
Median is preferred when a dataset contains extreme outliers or skewed distributions, such as household income figures.
Can I paste an entire spreadsheet column?▼
Yes, you can copy a column directly from Excel or Google Sheets and paste it into the input box.
Does it support negative numbers?▼
Yes, negative values are included accurately in all mathematical computations.
