Best ResponseYou've already chosen the best response.0goodTo divide the data into quarters, you then find the medians of these two halves. Note: If you have an even number of values, so the first median was the average of the two middle values, then you include the middle values in your submedian computations. If you have an odd number of values, so the first median was an actual data point, then you do not include that value in your submedian computations. That is, to find the submedians, you're only looking at the values that haven't yet been used

Best ResponseYou've already chosen the best response.0I have to make a box and whisker plot for the data shown at http://assets.openstudy.com/updates/attachments/5148e6dee4b05e69bfab6578help123please.1363732200597screenshot20130319at5.28.53pm.png

Best ResponseYou've already chosen the best response.2Find the median first Then split the data into two groups (the median is the cut off point) and find the median of each group. The first quartile is the median of the lower half, the third quartile is the median of the upper half

help123please.

Best ResponseYou've already chosen the best response.0the median is 68.

help123please.

Best ResponseYou've already chosen the best response.0oohhhh divide it into 2?

help123please.

Best ResponseYou've already chosen the best response.0so 4 sets of data in the lower quartile and 4 in the upper?

jim_thompson5910

Best ResponseYou've already chosen the best response.2yes the median is 68

help123please.

Best ResponseYou've already chosen the best response.0show me step by step how to make it using the DRAW button please?

jim_thompson5910

Best ResponseYou've already chosen the best response.2so the sorted number set 61, 64, 65, 68, 68, 70, 71, 73 turns into 61, 64, 65, 68  68, 70, 71, 73 when you split the data in half along the median

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2the median of 61, 64, 65, 68 is 64.5, so Q1 = 64.5

help123please.

Best ResponseYou've already chosen the best response.0i don't know how to get that...

jim_thompson5910

Best ResponseYou've already chosen the best response.2it's basically the distance from each endpoint of the box

jim_thompson5910

Best ResponseYou've already chosen the best response.2now find the min and max

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.0The min and max?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2yes, the smallest and largest data values

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.0oh... U mean min = 61 max = 73

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2good, now determine if the min is an outlier or not

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2you do this by seeing if the min is above median  1.5*IQR

jim_thompson5910

Best ResponseYou've already chosen the best response.2just a number that some statistician a long time ago determined was the best number to see if outliers exist on a box and whisker plot

Best ResponseYou've already chosen the best response.2I'm not sure how or why he got 1.5, but it works

jim_thompson5910

Best ResponseYou've already chosen the best response.2and people agree on it

jim_thompson5910

Best ResponseYou've already chosen the best response.2you just found it

jim_thompson5910

Best ResponseYou've already chosen the best response.2subtract that from the median 68

Best ResponseYou've already chosen the best response.0Hmm. Ok. WOW, lots of steps :/ LOL.

Best ResponseYou've already chosen the best response.2it's not so bad once you get used to them

jim_thompson5910

Best ResponseYou've already chosen the best response.2so that's your lowest threshold

help123please.

Best ResponseYou've already chosen the best response.0i punched the wrong numbers into the calculator.

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2basically that's the smallest the min can be

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.0sorry bout that.

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2any smaller than 59, and the min is an outlier

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2so we do NOT have an outlier for the min because the min (which is 61) is greater than the threshold of 59

jim_thompson5910

Best ResponseYou've already chosen the best response.2now compute median + 1.5*IQR

help123please.

Best ResponseYou've already chosen the best response.0Mhmm. Okay. One second  will log off for like 2 mins,k?

jim_thompson5910

Best ResponseYou've already chosen the best response.2did you find median + 1.5*IQR

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.0lets see. the median was?

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.068. so 689... 59?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2you already did that one

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.0its not the answer?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2no I wanted you to find median + 1.5*IQR

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2yeah but the IQR is 6, not 9

jim_thompson5910

Best ResponseYou've already chosen the best response.2good, is the max smaller or larger than 77?

help123please.
 2 years ago
Best ResponseYou've already chosen the best response.0The max is 73, so its larger.

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2you mean, the max is smaller than 77?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2so does that make the max an outlier?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2so there are no outliers

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2you're correct

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2so you have enough info to plot the box and whisker plot

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.2The basic format (the chances of your box and whisker plot looking exactly like this are very slim) is this dw:1363736245038:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.2dw:1363736267701:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.2this is if you don't have any outliers
