Question
15. The graph below shows health-care costs (in Euro) for handinjuries to young children, according to the cause of the injury: A) burn injuries caused by hot objects, B) fingertip injuries caused by jamming in doors or other pinch objects, C) fractures, dislocations and sprains caused by a fall or hit, D) tendon and nerve injuries and wounds caused by sharp objects, E) complex injuries (an injury to more than one of the anatomical components of the hand or total or subtotal amputation through the middle or proximal phalanges) caused by falls with sharpobjects, F)complex injuries caused by machines and rifles, and G) other injuries. 30,000 10,000 40,000 50,000 20.000 EUR cost per case or total cost? The potentialof prevention of hand injuries in young children Retrospective and prospective studies Elinor M Liungberg, Katarina Steen Lars B Dahlin BMC Pediatrics 2008; 28Explanation / Answer
while boxplot for A has many outliers (points outside the upper whisker) , there is only one point for D . Hence D points are more neatly spread around the median value
also we can see that the horizontal position of D boxplot is high as compre to A , which suggests that the central spread of the data is at a higher scale for D . In a nutshell , costs for D are higher than A but are more evenly spread when compred to A
d)
Likwise , we see that the box of the boxplot , the interquartile range for F is high as compared to D . Also the range of the cost values are overall highe then the range of the cost values for D. However , as we see the median line of F , the data appears to be skewed right , while D is quite close to normal distribution
e) not quite though , becuase the boxplots considers all the sample that are available while creating the boxplots. However , if the sample size is different then we cant be sure of how F boxplot would be if its sample size were to increase to that of D . If new samples are less in values , then it may shrink the box , if it has more extremes then we may have more outliers , if it has more higher or lesser acceptable values , then we may have a even wider box or the interquartile range.
