About Average Calculator
The average most people mean is the arithmetic mean: add up all the values and divide by how many there are. For the numbers 4, 8, 6, 5, 3 and 8, the total is 34 and there are six values, so the mean is 34 ÷ 6 ≈ 5.67.
Mean, median and mode
The mean uses every value, which makes it sensitive to one unusually large or small number. The median is the middle value once the numbers are sorted — for 3, 4, 5, 6, 8, 8 there are two middle values, 5 and 6, so the median is 5.5. The mode is the value that appears most often: 8 in this example.
Which one should you use?
Use the mean for things like average marks or average daily sales, where every value matters. Use the median when a few extreme values would distort the picture — salaries and house prices are usually reported as medians because a handful of very high figures pull the mean upwards. Use the mode for "most common" questions, such as the most popular shoe size.
Weighted averages
If some values count for more than others — an exam worth 60% and coursework worth 40% — multiply each mark by its weight, add the results and divide by the total of the weights. A plain average would treat both parts as equal and give the wrong grade.
Common mistakes
Averaging percentages from groups of different sizes gives a misleading result; combine the underlying totals instead. And averaging averages only works when every group is the same size.
