Graphical Method of Chi-square Test

Abstract

We have discussed a new graphical method, for the chi-square test, which we call “the method of chi-square paper.” Using our method, we solved the problem of 2×2, 2×n, and m×n classification and their references with sufficient rapidity and accuracy. It is not only applicable to a small sample but more effectively to such a smaple having the large size and very small rate as appears in the public health statistics, especially in the vital statistics.
