What is an Average?
An average is a single number that represents the “middle” or typical value in a set of numbers. It helps simplify data by giving you one meaningful number instead of a long list.
The most common types are the mean (sum divided by count), median(middle number), and mode (most frequent number). Averages are used everywhere—from grading tests to analyzing business profits—because they turn raw numbers into useful information.
What Does This Calculator Do?
Simply type in your numbers (separated by commas or spaces), hit Calculate, and get:
✔ Mean (Average) – The sum of all numbers divided by how many there are
✔ Median – The middle number in an ordered list
✔ Mode – The number that appears most often
✔ Range – The difference between the highest and lowest values
✔ Sum – The total of all numbers added together
✔ Min & Max – The smallest and largest numbers in your set

How to Calculate Averages (Simple Examples)
1. Finding the Mean (Average)
Example: You scored 85, 90, 78, and 92on four tests. What’s your average?
- Add them up: 85 + 90 + 78 + 92 = 345
- Divide by 4 (number of tests): 345 ÷ 4 = 86.25
✅ Your average score is 86.25
2. Finding the Median
Example: Ages of siblings: 12, 7, 19, 5, 10
- Sort them: 5, 7, 10, 12, 19
- Pick the middle number: 10
✅ The median age is 10
What if there’s an even amount of numbers?
Example: 3, 7, 12, 15
- Middle two numbers: 7 & 12
- Average them: (7 + 12) ÷ 2 = 9.5
✅ The median is 9.5
3. Finding the Mode
Example: Number of pets in different homes: 1, 3, 3, 5, 2, 3, 1
- Count how many times each appears:
- 1 → 2 times
- 2 → 1 time
- 3 → 3 times (most frequent)
- 5 → 1 time
✅ The mode is 3
What if no number repeats?
Example: 2, 5, 9, 11
✅ There is no mode
