# Mean Calculator Calculate the arithmetic mean of a numeric dataset and review the main supporting statistics > Canonical page: https://elysiatools.com/en/tools/mean-calculator - **Category:** Math & Numbers - **Keywords:** mean, arithmetic mean, average, statistics, dataset, math ## Overview The Mean Calculator is a straightforward utility designed to compute the arithmetic mean of any numeric dataset. By simply pasting your numbers into the tool, you can instantly find the average value while optionally reviewing supporting statistics like the total sum and count. It is ideal for students, researchers, and analysts who need quick, precise calculations with customizable decimal formatting without relying on complex spreadsheet software. ## Inputs - **Dataset** (textarea): e.g. 12, 18, 24, 30 - **Decimal Places** (number) - **Include Supporting Statistics** (checkbox) ## When to use - When you need to quickly find the average value of a list of numbers without setting up spreadsheet formulas. - When analyzing survey results, test scores, or financial data to determine the central tendency of a dataset. - When you require both the arithmetic mean and supporting statistics like the total count and sum in a single, easily readable output. ## How it works - Paste or type your numbers into the Dataset input field, separating them with commas or spaces. - Specify the number of decimal places you want in the final result, choosing any value between 0 and 10. - Toggle the 'Include Supporting Statistics' option if you want to see additional data like the count and sum. - Run the tool to instantly generate a JSON output containing the calculated mean and your requested statistics. ## Use cases - Teachers calculating the average exam scores for a classroom to evaluate overall student performance. - Financial analysts determining the average daily closing price of a stock over a specific period. - Researchers finding the mean value of experimental data points while reviewing the total sample count. ## Frequently asked questions ### What format should my dataset be in? You can enter your numbers separated by commas, spaces, or newlines directly into the text area. ### Can I control the rounding of the result? Yes, you can adjust the 'Decimal Places' setting from 0 to 10 to round the calculated mean exactly as needed. ### What are the supporting statistics? When enabled, the tool provides additional context about your dataset, such as the total number of items (count), the sum of all values, and the spread. ### Is there a limit to how many numbers I can input? The tool can handle large datasets as long as they can be pasted into the text area, making it suitable for most everyday statistical tasks. ### Does this calculate the median or mode? No, this specific tool calculates the arithmetic mean (average) and basic supporting statistics. It does not calculate median or mode. ## Related tools - [Average Calculator](https://elysiatools.com/en/tools/average-calculator): Compare arithmetic, geometric, and harmonic averages for a numeric dataset in one place - [Cam Follower Displacement Calculator](https://elysiatools.com/en/tools/cam-follower-displacement): Calculate the follower displacement, velocity coefficient, acceleration coefficient and pressure angle during the cam rise phase.

Parallel flow: ΔT₁ = T_h,in - T_c,in and ΔT₂ = T_h,out - T_c,out; counter flow: ΔT₁ = T_h,in - T_c,out and ΔT₂ = T_h,out - T_c,in. LMTD = (ΔT₁ - ΔT₂)/ln(ΔT₁/ΔT₂), or ΔT₁ when ΔT₁ = ΔT₂. A non-positive terminal difference (temperature cross) is physically impossible and is rejected. Optionally, with the overall heat transfer coefficient U (W/(m²·K)) and the heat transfer area A (m²), the heat transfer rate Q = U·A·LMTD (W) is returned. Temperatures are used only as differences: Δ°C = ΔK and Δ°F ×5/9 = ΔK; the LMTD is reported in K. - [Normal Distribution Calculator](https://elysiatools.com/en/tools/normal-distribution-calculator): Calculate z-scores, cumulative probability, tail probability, and interval probability for a normal distribution - [Inverse-Time Overcurrent Relay Setting (IEC 60255-151)](https://elysiatools.com/en/tools/relay-setting-calculator): Compute the operating time of an inverse-time overcurrent relay per IEC 60255-151: t = TMS·(k/((I/I_s)^α − 1)).
