the mode for class A ..you have to look at my post under classA to see which # occurs the most
anonymous
  • anonymous
I think it's class A .
LynFran
  • LynFran
so far im seeing B as the answer... but lets check for the median for class B|dw:1437513187727:dw|
anonymous
  • anonymous
I was talking about class A. :P
anonymous
  • anonymous
I think the answer is B
LynFran
  • LynFran
to find the median we arrange the # from smallest to largest as look for the middle # so 41, 42, 59, 62, 64, 69, 71, 75, 77, 78, 78, 80, 83, 84, 84, 86, 86, 87, 92, 92, 95...now which # is directly in the middle
