U Test Failed

Your U test failed. Probably you gave it invalid inputs: n1 and n2 must be positive integers, and U, if correctly calculated, will be between 0 and n1 × n2. dataset 1 and dataset 2 must each be a list of numbers separated by commas or spaces. If any contain decimals, you must use '.', not ',' before the fractional part. (E.g, '5.25' -- '5,25' will be read as two numbers: '5' followed by '25'.)

Try again:

Use this form if you have calculated the Mann-Whitney test statistics n1, n2, and U:
n1:
n2:
U:

Use this form if you want the statistics calculated for you. Paste into each box a list of numbers:
dataset 1:
dataset 2:
Use "." for decimals, not ",".

If your numbers are large, be patient -- the calculation may take a minute or two. Don't reload -- that will only slow the response down.
