Abstract

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