Developing Knowledge for Teaching Graphing of Bivariate Categorical Data

Speaking Stata: Graphing categorical and compositional data

Abstract. A variety of graphs have been devised for categorical and compositional data, ranging from widely familiar to more unusual displays. Both official Stata commands and user-written programs are available. After a stacking trick for binary responses is explained, bar charts and related displays for cross-tabulations are discussed in detail. Tips and tricks are introduced for plotting cum...

Displaying Bivariate Data

Numerical techniques are too often designed to yield specific answers to rigidly defined questions. Graphical techniques are less confining. They aid in understanding the numerous relationships reflected in the data. They help reveal the existence of peculiar looking observations or subsets of the data. It is difficult to obtain similar information from numerical procedures. In this article, by...

Graphing Calculators and Their Potential for Teaching and Learning Statistics

The world today is described as a world based on information (National Council of Teachers of Mathematics, 1989), and reports on the rapid increase of information use figures such as " doubling every four years " or " increasing exponentially. Technology is not only responsible for producing much of this information, it is a critical tool in the way information is analyzed. Processing informati...
