Average in plain language
Average usually means arithmetic mean. Add all the values, then divide by how many values you entered.
For 10, 12, 12, 15, and 18, the sum is 67. There are 5 values, so the average is 67 / 5 = 13.4.
Why the extra summary matters
A single large or small value can pull the average away from what most values look like. That is why the calculator also shows median, mode, and range.
Use the average for a quick center point, then glance at the range and sorted values before you decide what the data is really saying.
Examples from the calculator
