Average Calculator
Calculate the mean, median, mode, count, and sum of any list of numbers.
About the Average Calculator
"Average" can mean several different things depending on context — mean, median, or mode all describe the center of a data set differently. This calculator computes all three at once from any list of numbers, along with the count and sum, so you can see the full picture.
How It Works
The calculator parses your list of numbers, then computes the mean by summing all values and dividing by the count, the median by sorting the values and finding the middle one (or averaging the two middle values for an even-sized list), and the mode by finding whichever value or values occur most frequently.
Mean = Sum / Count. Median = middle value of sorted list. Mode = most frequently occurring value(s).
Example
Scenario: The data set 4, 8, 6, 5, 3, 8.
Result: Mean of 5.67, median of 5.5, mode of 8 (the only repeated value), and a sum of 34 across 6 numbers.
Assumptions & Limitations
- Non-numeric entries in the list are ignored automatically rather than causing an error.
- If no value repeats more than once, the mode is reported as 'None' since there is no single most-frequent value.
- Mode reporting shows all values tied for most frequent if there is a tie, rather than picking just one arbitrarily.
