what number of numbers are in the middle?  that might help to rule out the median

amistre64 · Answer

is there another 250 in the set?  and how does that relate to the mode?

amistre64 · Answer

120, 128, 135, 140, 147, 148, 148, 154, 156, 158, 165, 166, 166, 172, 174, 174, 175, 177, 180, 183, 189, 190, 192, 196, 206, 225

if large numbers are scary ... we can reduce this to an equivalent set by subtracting 120

  0,   8, 15, 20, 27, 28, 28, 34, 36, 38, 45, 46, 46, 
52, 54, 54, 55, 57, 60, 63, 69, 70, 72, 76, 86, 105

now including 135 changes what?
