49. As a part of a study to determine factors influencing mortality in an intensive care unit, serum creatinine concentrations (in mg/dL) are obtained from 10 consecutive patients at the time of admission to the intensive care unit. The results are shown in the graph. Which of the following statements regarding the sizes of the mean, median, and mode of the serum creatinine values is correct?

even though looking at it it looks like a negatively skewed ...but in my opinion it is positively skewed graph...because more patients have a lower value while only last 3 people have higher values...so if this is a positively skewed graph..then shouldnt the answer be A

I agree with you.. At the first glance it does look like its negatively skewed.. But, if you look closely, the actual distribution curve ( with creatinine on X axis and No of people on Y axis) should be a positively skewed one.. you're right.. answer would be A)

i think the answer is A also but not based on +ve and -ve skewed, i dnt get how u guys go that if u can explain that would be nice ( and helpful )
As far as +ve and - ve skew goes.
A and C both are true when it comes to distribution that is +vely skewed.
B and D are both true about -ve skewed.
But i also agree with it being A because if u look at graph u can see the median will be 1 and you can just estimate mean will have to be more because smallest value is .5 anyway. i dnt know =/
