Average Calculator

This online average tool lets the user quickly compute key statistics from any list of figures. From a single data entry, it will display the Mean, Median, Mode and Range, and can also generate additional values like standard deviation so you see the total picture of your data at a glance.

Type or paste your input into the large box as a series of numbers. Each value can be separated by commas, spaces or new lines. Every entry is automatically processed so the calculator can determine the correct result without you worrying about formatting.

Yes. You can copy a column or row of numbers from a spreadsheet and paste it directly into the calculator. Each line will become a separate entry, and the tool will analyze the data and compute all required outputs like mean and median.

All three are ways to average a data set, but they highlight different aspects of your numbers:

• Mean is based on the sum of all values divided by how many there are.
• Median looks at the middle value in the ordered list.
• Mode shows the number that appears most often.

Using all three together helps you better compare and analyze your results.

Just enter your data and click the button. The calculator will compute the minimum and maximum value, then display the Range as their difference. This output shows how far apart the lowest and highest score or measurement are in your data.

Use the geometric mean when you deal with percentage changes or growth over time, such as investment returns or population growth. Instead of a basic arithmetic equation, it works with products of values, making it more accurate and reliable for multiplicative data patterns.

Standard deviation is an advanced statistic that shows how much the values in your data set vary around the mean. A low value means most figures are close to the average; a high value means they’re more spread out. It’s especially useful when you want to compare consistency between different results or data sets.

Yes, the calculator is designed to process many kinds of input: whole numbers, decimals and negative values. You can work with long lists of data, and the tool will still compute a fast, efficient output for every supported statistic.

• Use the mean when you want a basic digital “overall” value and your data doesn’t contain extreme outliers.
• Use the median for skewed data, such as incomes or property prices, so one very high or low figure doesn’t distort the result.
• Use the mode when you’re looking for the most frequent score or category, like popular product sizes or survey choices.

No. This free, user-friendly calculator works in real-time and is not designed to store or update your data after the result is generated. Once you clear the input box or leave the page, your entries and outputs are not kept, which helps protect sensitive information.
