The core descriptive stats for a list of numbers, all in one place.
Mean is the sum of all values divided by how many there are — it's pulled toward extreme values. Median is the middle value once the numbers are sorted (or the average of the two middle values for an even count), so it's less affected by outliers.
Yes. If two or more values tie for the highest frequency, this calculator lists all of them together. If every value appears exactly once, it shows "None" since there's no most-frequent value.
With an odd count, there's a single true middle value once sorted. With an even count, there are two middle values, so the median is defined as their average — that's why the formula branches on odd vs. even.
