This chapter aims to do two things. Part A focuses on how to estimate statistics, particularly the mean and standard deviation, from data that is only presented in summary form (like a frequency table or a histogram). Part B takes this one step further, by helping you connect two different ways of picturing data by relating histograms and boxplots. Both give a picture of how the data is spread out. The difference is that a boxplot takes the data and breaks it into four chunks with the same number of observations in each chunk, but with each chunk of data having a different length. Histograms are the opposite: each chunk has exactly the same length, but probably has different numbers of observations in it.
