Frequently Asked Questions
What is an average (mean)?
The average, or mean, is the sum of all numbers divided by how many numbers there are. It represents the central tendency of a dataset and is the most commonly used measure of center in statistics.
What is the difference between average (mean) and median?
The average (mean) is the sum of all values divided by the count. The median is the middle value when numbers are arranged in order. The median is less affected by extreme values (outliers) than the mean.
What input formats are accepted?
You can enter numbers separated by commas, spaces, new lines, or a combination of these delimiters. For example: "10, 20, 30", "10 20 30", or numbers on separate lines all work correctly.
Can I use negative numbers and decimals?
Yes, absolutely. The calculator supports negative numbers, decimals, and very large numbers. Simply enter them like any other number (e.g., -5.5 or 100.25).
How many numbers can I average?
There is no practical limit to the number of values you can average. You can enter as many numbers as you need, and the calculator will process them all to calculate the mean, median, and other statistics.
What is the formula for average?
The average (mean) formula is: Average = (x₁ + x₂ + x₃ + ... + xₙ) ÷ n, or in mathematical notation: μ = Σ(xᵢ) / n where n is the count of values. This calculates the sum of all values divided by the number of values.
Pro Tips
- • Copy and paste data directly from spreadsheets like Excel or Google Sheets - the calculator will parse it automatically.
- • Use the median for datasets with outliers, as it is more resistant to extreme values than the mean.
- • The range (max - min) tells you the spread of your data - a larger range indicates more variation.
- • For skewed distributions, the mean and median will differ. Compare both to understand your data better.
- • Negative numbers are fully supported - use them for losses, debits, or downward adjustments in your dataset.
- • Decimal numbers are supported, making this calculator useful for precise financial, scientific, or survey data analysis.
