Review Statistics
See the average (mean), sum, minimum value, maximum value, and range displayed with the formula.
Formula
Average (Mean) = Sum of Numbers ÷ Count of Numbers
Or: μ = Σx / n
Example 1: 10, 20, 30
Sum = 10 + 20 + 30 = 60
Count = 3
Average = 60 ÷ 3 = 20
Example 2: 5, 10, 15, 20, 25
Sum = 5 + 10 + 15 + 20 + 25 = 75
Count = 5
Average = 75 ÷ 5 = 15
Example 3: 1.5, 2.5, 3.5
Sum = 1.5 + 2.5 + 3.5 = 7.5
Count = 3
Average = 7.5 ÷ 3 = 2.5

Understanding the Average (Mean)
The average, also called the arithmetic mean, represents the central value of a dataset. It's calculated by summing all numbers and dividing by the count of numbers.
- Best for: Data with normal distribution and no outliers
- Affected by: Extreme values (outliers) can skew the result
- Always: Falls between the minimum and maximum values
- Balance point: Sum of deviations above and below average equals zero
Additional Statistics Shown
- Sum: Total of all numbers
- Minimum: Smallest value in the dataset
- Maximum: Largest value in the dataset
- Range: Maximum - Minimum (spread of data)
Real-World Applications

Frequently Asked Questions
What's the difference between average, median, and mode?
Average (mean) is the sum divided by count. Median is the middle value. Mode is the most frequent value. For 1,2,3,4,100: average=22, median=3, mode=none.
Can I find the average of negative numbers?
Yes! The calculator works with negative numbers. For example, the average of -10, 0, 10 is 0.
What if I enter non-numeric characters?
Non-numeric values are automatically filtered out. Only valid numbers are used in the calculation.
Can I use decimals or fractions?
Yes! Decimal numbers work perfectly. For fractions, convert to decimals first (1/2 = 0.5).
How many numbers can I enter?
The calculator can handle any number of values. Just separate them with commas!
Is the average affected by outliers?
Yes, unlike median, average is sensitive to extreme values. One very high or low number can significantly change the average.
