i have two questions...but cant really figure them out...can someone help?? i will fan or medal or do both
post your question
k, one sec
What is the first quartile (Q1) of the data set? 51, 42, 46, 53, 66, 70, 90, 70 48.5 59.5 61 70
first off, you'll need to find the median. To do that, you sort the data from smallest to biggest and pick out the middle-most value
what median do you get?
i got 46
sorry wrong answer lol
59.5 is my real answer that i got
59.5 is the median, yes
k whats the next step?
what we do from here is cut the data set in half based on that median the first quartile will come from this data set circled |dw:1433221087759:dw| I have circled everything smaller than the median
find the median of that subset, of this list of numbers 42, 46, 51, 53 to get the value of Q1
48.5 is Q1, correct
yay!!! can you help with one more...its for Q3
k thanks! :)
What is the third quartile (Q3) of the data set? 165, 85, 105, 105, 152, 144, 140, 160, 80 105 140 156 160
you'll follow the same steps, but instead of focusing on the lower half, you do the upper half
k, ill try and find the answer now....
step 1) sort the data step 2) find the median step 3) circle the group of values larger than the median or to the right of it step 4) in this sub-group, find the median to get Q3
i got 156...is that correct?
Q3 = 156 is correct
yay!! and thank you so much! you are very kind! :)
glad to be of help
