bar chart Quick reference
A graphic means of displaying a *frequency distribution of quantitative data. Blocks proportional in width to the size of the categories are raised along the horizontal axis. The height of each block is then adjusted so that its area is proportional to the relative frequency of its category. The chart appears as a series of bars of varying height, as in the hypothetical example in the first figure, which shows the number of births in a hospital for each day of the week....
causal modelling Quick reference
A causal model is an abstract representation of real-world dynamics that attempts to describe the causal and other relationships, among a set of variables. The best-known form of causal modelling is ...
correspondence analysis Quick reference
A statistical method for analysing cross-tabulated data by finding a geometrical representation of the structures of the table. Such tables might combine, for example, social class and music preference. The rows and columns of the table are depicted as clouds of points in a multidimensional space, one point for each row or column, as shown in the Figure. Well-known applications of correspondence analysis are the diagrams presented by ...

pie chart Quick reference
A form of descriptive statistics in which data are presented graphically or pictorially as in the hypothetical illustration shown here. It gives the relative proportions of people who are admitted to universities, based on social-class background. The distribution has been divided into four social classes (salariat, self-employed, routine clerical, working class), and the ‘pie’ has been divided into ‘slices’ proportional in size to the frequency of university admission in the various categories. The principal advantage of this way of presenting data is that it makes it easy to see the proportion of the total pie obtained by each category. Where the primary intention of the presentation is to compare the relative sizes of categories then a conventional ...
