Results from one exercise can bereused for other exercises if you refer to them explicitly.As a young researcher you immediately see the opportunity to apply your knowledge instatistics by describing the sample using methods from descriptive statistics:1. Concentrate on the variables "sex" and "weight" for this exercise: Is it possible todraw a meaningful boxplot for each of the two variables? Explain! Calculate thenecessary numbers and sketch the meaningful boxplot(s). If you do not draw twoboxplots: What sort of figure can be drawn to sketch the distribution of the other ofthe two variables "sex" and "weight"? Draw that figure as well and explain why youhave chosen it.- EED -
