About Averages & Ratios Calculators

Averages and ratios let you summarise and compare data. The mean, median, and mode each tell a different story about a dataset, and choosing the right one matters. Ratios and proportions are fundamental to scaling, map reading, cooking, and engineering.

Who uses these tools: Teachers grading on a curve, scientists summarising experimental results, cooks scaling recipes, and engineers designing scale models all work with averages and ratios regularly.

Tips for best results: When data has extreme outliers (very high or very low values), the median is often a better summary than the mean. Use the average calculator to compute both at once and decide which is more appropriate for your data.
