Mean = sum / count; median is the middle sorted value. Quartiles use the linear-interpolation method (the same as Excel QUARTILE.INC).
Find mean, median, mode, sum, range and quartiles from your list, with every value plotted on a number line.

Find mean, median, mode, sum, range and quartiles from your list, with every value plotted on a number line.
For 10, 20, 30, 40 the mean and median are both 25, the sum is 100, the range is 30, there is no mode, and the quartiles are 17.5 and 32.5. For 1 to 10 the quartiles are 3.25 and 7.75.

It is a visual aid, not a replacement for the numeric output. Some charts compare values with different units, and those magnitudes are not directly comparable.
Check units, signs, assumptions and rounding first. The tool cannot know whether the values you enter describe the real situation correctly.
