both A & C are suitable for positive deviation. i dunno which is correct for this.

a is the right answer bc last 3 valuses r much larger as compared to rest of the values and r responsible for making mean larger than median.its positively skewed distribution.

I go with D
Patient 5 and patient 6 have same value--> mode = 2
Median is between patient 5 and patient 6---> median=1
Mean= values of 10 patient/10, think about calculation, total 10 values>10 but <20---> mean is somewhere between 1 and 2.
Thus D is correct.

robin, i dint get u. can u plz explain in some detail.
pt 5 & 6 have same value, mode = 1 (not 2 as u posted)
median = 1
so mode and median r approximately equal

A. Both Mean and Median here are roughly 1.
And the mean is greater than 1.

Mode is the number of value that is most repeated. Patient 5 and P6 have repeated (equal) value, so mode=2. If there are 3 patients having the same value, mode=3, n patients having same value, mode=n.
Median is the mid-value. There are 10 patients, so mid-value is between p5 and P6, value of P5=1, and P6=1 so median = 1. If value of P5=1 and P6=2 then median=1.5.
Hope you understand.

robin,, i think u missed it somehow. acc to kaplan "mode is the most frequently occuring value" so in the above case it will be 1..

For negative skewed distribution, mode>Median>mean
Positive distribution, mean>median>mode
This is a sort of negative. That will be much easier.

Mean in this question is 1.XYZ
Mode is 1.0 ..
So therefore Mean is Greater than Median ..
A thus being the answer

answer is D
Mean = add everything/10=5.5
median = middle number =5.5
mode = largest number = 10
so D is the answer

Mode is not the largest number. Mode is the most frequent value in a group of values, which is definitely not 10 !!!
The answer is A

The answer is mostly A. The graph is drawn in a way to divert our attention to a L (-) skewed !!!!!! but it's a R (+) one. Coz most values r low & only 3 r very high. Pretend a gaussian that the L side is omitted ( very low values in a few # r omitted, but very high values in a few # of cases r present id. cr 2.5, 4 & 5.5 in Ps 8, 9 & 10 ).
Median is related to Ps 5 & 6. If u look so carefully, no two values r equal, but if we insist Ps 5 & 6 have at least nearly equal values, so mode & median r equal.
I hope I could help u.

The Ans should be A,
Mean=10 Value /10, cs there are 5.5 and 4.5, so mean > 1 for sure.
Median is the point divide the group into two, either above or below, here =1
mode is the most repeated value in the group, here p5=p6=1, so mode =1
