these are the 5 numbers you're looking for in each group. minimum → lowest number 1st quartile → median of the lower half of numbers median → middle number 3rd quartile → median of the higher half of the numbers maximum → highest number Which ones do you know how to find?

can you pick out the maximum and minimum in group A
anonymous
  • anonymous
21 25
anonymous
  • anonymous
right. now pick out the median. what number is in the middle of group A?
anonymous
  • anonymous
use the list you wrote in order to pick it out
anonymous
  • anonymous
23
anonymous
  • anonymous
yes that's right. now for the 1st quartile look at the numbers left of the median. They are 21, 22, 22, and 23. We need to find their median. Since it's an even amount of numbers, there you can't just pick it out. We have to add the 2 middle numbers and divide by 2. 1st quartile = (22 + 22)/2 = 22

Does that make sense?
anonymous
  • anonymous
yes
anonymous
  • anonymous
great. so for the 3rd quartile you need to look at the numbers right of the median. So what is the median of 23, 24, 24, and 25?

anonymous
  • anonymous
I don't understand
anonymous
