How do you describe a distribution?
- mention center, shape, and spread in context
What about comparing two distributions?
- describe the shape of both distributions
- compare the centers and spreads - example the median of the distribution of length of signature for the females is larger than the signature length for males. The IQR of the male signature lenghts is larger than the IQR of female signature lengths. No credit is given for just listing measures of center and spread.
What kinds of graphs can be used to describe univariate data?
- dotplot
- stem & leaf plot
- histogram
- boxplot
- normal probability plot
