I need help because the last person that helped with this question made me click a link and it made me download a bunch of virus-helping apps and they are so annoying. And I never even got the darn answer!

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

what am i trying to find out. you didn't put up the whole question.

step-by-step explanation:

so mark-up is 0.4 multiplied by 180 = 72
