Blood proteins in children from Papua New Guinea. C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within 6 hours of an infection and reach a peak within 24 to 48 hours. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children.29 The units are milligrams per liter (mg/l). Here are the data from a random sample of 40 of these children: 0.00 3.90 5.64 8.22 0.00 5.62 3.92 6.81 30.61 0.00 73.20 0.00 46.70 0.00 0.00 26.41 22.82 0.00 0.00 3.49 0.00 0.00 4.81 9.57 5.36 0.00 5.66 0.00 59.76 12.38 15.74 0.00 0.00 0.00 0.00 9.37 20.78 7.10 7.89 5.53 (a) Find the five-number summary for these data. (b) Make a boxplot. (c) Make a histogram. (d) Write a short summary of the major features of this distribution. Do you prefer the boxplot or the histogram for these data?
