Question 1

What's the difference between this and the Mean, Median, Mode & Range calculator?

Accepted Answer

That calculator gives you the full statistical picture — mean, median, mode, range, and more, all at once, aimed at a full data-analysis pass. This Average Calculator is deliberately narrower: it's built for the everyday moment you just need one number, the plain average, plus the option to weight some values more heavily than others — a mode the full stats tool doesn't offer.

Question 2

How is a weighted average different from a regular average?

Accepted Answer

A regular average treats every number equally — add them up, divide by the count. A weighted average lets some numbers count more than others by multiplying each value by its own weight before averaging: weighted average = Σ(value × weight) ÷ Σ(weight). It's the exact math behind a GPA, where a 4-credit class pulls your average harder than a 1-credit one.

Question 3

When would I actually need a weighted average?

Accepted Answer

Anywhere different data points carry different importance: course grades weighted by credit hours, a portfolio's return weighted by how much money is in each holding, or a survey where responses from different group sizes need proportional weight. If every input matters equally, stick with the simple average.

Question 4

Does a large outlier distort the average?

Accepted Answer

Yes — the plain mean is sensitive to extreme values, since every number pulls the total equally regardless of how far it sits from the rest. If one number in your list is far larger or smaller than the others, look at the min/max shown alongside your result and consider whether the median (from our full statistics calculator) tells a more representative story.

Question 5

How many numbers can I enter?

Accepted Answer

As many as you need — add rows one at a time and every result updates live as you type. There's no practical limit for a typical list of grades, scores, or measurements.
