What it does
Calculators.org offers browser calculators grouped around mathematics, savings, borrowing, business and health topics.
Use the subject navigation to choose a mathematical or practical worksheet. The mean/median/mode tool accepts a comma-separated number list and returns those summaries, the range, count and ordered values. Its arithmetic mean sums entries and divides by their count, so every entered value has equal weight. For an even count, the median averages the two central ordered values; the range is largest minus smallest. Those outputs answer different questions about the same data. The collection is free and requires JavaScript. Its loan, savings and health pages use separate models and assumptions.
