While a dot plot depicts data on quantitative variable without distortion, boxplot shows only the five-number summary. For large data, to aid in counting, we propose an IVY as companion plot. Also, for if is approximately normally distributed, boxplot, Gaussian interval that summary, mean, SD, sample size, and counts of outliers. We hope these enhanced visualizations will add value commonly use...

Abstract: QQ-plots are extremely useful in univariate data analysis. In this article, Koltchinskii (1997) and Chaudhuri’s (1996) definition of multivariate quantile is used to develop analogous plots for bivariate data. Bivariate qq-plots are exhibited for comparing a sample to a given population distribution (the bivariate normal), and for comparing two or more bivariate samples. The plots are...
