sahusemaWow. I hate this. I only looked at the number of participants and completely ignored the Diastolic BP readings+12019-07-18T18:15:17Z
fadilamedian should be: 70 for group X ; 85 for group Y
median here is the avarage of Diastolic BP measured betweeen the 50 & 51 patients (since the number of patients in each group in even; Median= (n+1)/2 -> (100+1)/2= 50.5)
Group X = (70+70)/2 = 70
Group Y = (80+90)/2 = 85+2019-11-05T13:45:27Z
yb_26tried to attach photo, sorry for that(+2019-07-04T18:37:29Z
hungryboxJust checking in so I could feel smart about getting this right despite bombing the rest of the test lmao+22019-05-31T14:03:31Z
usmleuser007can someone please explain the median in this+2019-06-10T02:39:38Z
nala_ulaThe median can be known by first assembling the numbers in order from least to greater.
If it's an uneven number set, the number in the middle is the median (for example: 4, 10, 12, 20, 27 = median is 12 since this is the number in the middle); if the numbers are even then you have to take the two values in the middle, add them up and divide them by 2 [for example: 4, 10, 12, 12, 20, 27 = (12+12)/2 = 12].
Page 261 on FA 2019 explains it as well. Not sure if I explained it well... good luck on the test, people! +2019-06-17T00:17:13Z
dubin johnsonCan someone please explain how the mode for Y than X. Not sure how we got the values above. Thanks!+2019-06-20T21:08:51Z
dubin johnsonI mean how is the mode for Y greater than mode for x?+12019-06-20T21:10:49Z
sgarzon15Mode is the one that repeats the most once you list them in order+2019-06-21T01:51:44Z
usmile1Median would be the BP value that the person in the 50th percentile of each group would have.
So for group X, to find the 50th percent value, I added 8 + 12 + 32 = 52, which is right above 50, so the median would be 70 mmHg for group X.
Doing the same thing for group Y, 2+8+10+20+ 18 = 58; the 50th percentile would fall in group that had a BP of 90 mmHg. which makes the median higher for group Y.
hope that isn't wrong, and helps someone!+42019-06-26T23:19:12Z
