Printout with summary statistics by disease subgroup for hemoglobin levels. Find medians, means, ranges, interquartile ranges, and standard deviations for hemoglobin levels by disease types.
2. Box plots and histograms by disease subgroups for the variable hemoglobin. Does the distribution of hemoglobin appear to differ between acyanotic and cyanotic children with congenital heart disease?
3. Based on summary measures and plots, your opinion as to the appropriateness of comparing values of central tendency in hemoglobin levels between acyanotic and cyanotic children.
4. Printout with values of the geometric mean by disease subgroup for hemoglobin levels. Verify the relationship that the arithmetic mean ο₯ geometric mean within each disease subgroup. Among the three measures of central tendency (arithmetic mean, geometric mean, and median), which best represents the central location of the data for children with acyanotic congenital heart disease? With cyanotic heart disease?
