Calculate mean, median, mode, and range of numbers instantly
What is Average Calculator? An average calculator computes statistical measures of central tendency. Mean equals sum of values divided by count. Median is the middle value when sorted. Mode is the most frequent value. Range equals maximum minus minimum. Example: For numbers 10, 20, 30, mean = 20, median = 20, range = 20.
💡 Tip: You can use commas, spaces, or new lines to separate numbers
📊 Statistical Measures
Mean (Average)
Formula: Mean = (Sum of all values) ÷ (Number of values)
Use: Best for datasets without extreme outliers
Median
Definition: The middle value in a sorted dataset
Use: Better than mean when data has outliers
Mode
Definition: The most frequently occurring value
Use: Useful for categorical or discrete data
Range
Formula: Range = Maximum value - Minimum value
Use: Shows the spread or dispersion of data

Frequently Asked Questions
How do you calculate the average (mean)?
Average or mean equals the sum of all numbers divided by the count of numbers. Formula: Mean = (Sum of all values) ÷ (Number of values). Example: Average of 10, 20, 30 equals (10+20+30) ÷ 3 = 20.
What is the difference between mean, median, and mode?
Mean is the average (sum ÷ count). Median is the middle value when numbers are sorted. Mode is the most frequently occurring value. Each measures central tendency differently.
How do you find the median?
Sort numbers in order. For odd count, median is the middle number. For even count, median is the average of the two middle numbers. Example: For [1,2,3,4,5], median is 3.
What is range in statistics?
Range is the difference between the largest and smallest values in a dataset. Formula: Range = Maximum value - Minimum value. It shows the spread of your data.
Can I calculate average of negative numbers?
Yes! This calculator works with positive numbers, negative numbers, decimals, and fractions. Just enter them separated by spaces or commas.
