In the Japanese current curriculum of mathematics for upper secondary schools which was implemented in 2013, the new statistical content called “Analysis of data” was included in “MathematicsⅠ” regarded as the core subject. The aims of it was to enable students to understand the basic concepts of statistics, and to arrange and analyze data using their concepts, and to grasp trends in the data correctly. In statistical lessons, we deal with the concepts of interquartile deviation, variance, standard deviation and box-and-whisker plot to grasp the variability of data, and the concepts of scatterplot and correlation coefficient to grasp the correlation of data. This paper illustrates the characteristic of statistical contents in the Japanese curriculum and the statistical lesson focused on the box-and-whisker plot.
