Abstract
This study analyzes the characteristics of dot plots and box plots that have been identified to be effective in developing the understanding of distribution and variability. Moreover, the study examines the use of dot plots and box plots in statistical teaching and learning and discusses the utility in Korean mathematics curriculum. With respect to the results obtained, the dot plot is firstly expected to bridge the gap between the elementary and middle school curriculum since the dot plot has a very simple system that can be used to construct and express a distribution by dealing with numerical data even at the elementary school level. Secondly, box plots aid in comprehensive understanding of distribution concepts and summary concepts. These concepts are expected to help establish links of statistical content elements that are currently perceived segmentally within the middle school curriculum. Third, dot plots and box plots provide an experience of an informal inferential reasoning for data sets at the elementary and middle school levels, and are expected to be a springboard for learning formal statistical reasoning that will be addressed later in high school.
