distributions of univariate data Summarizing distributions of univariate data Comparing distributions of univariate data Exploring bivariate data Exploring categorical data find center and spread of data recognize clusters and gaps determine outliers and other unusual features visualize shape of curves measure center: median, mean measure spread: range, interquartile range, standard deviation measure position: quartiles, percentiles, standardized scores (z-scores) gather information from boxplots see the effect of changing units on summary measures compare center and spread: within group, between group variation compare clusters and gaps compare outliers and other unusual features compare shapes analyze patterns in scatterplots calculate correlation and linearity find the least squares regression line graph residual plots, outliers, and influential points use transformations to achieve linearity: logarithmic and power transformations 19) 20) 21) 22) use frequency tables and bar
