p values were calculated in R statistical software (version 3.0.3) using an unpaired t test, an unpaired t test with Welch’s correction for unequal variances, or a Wilcoxon rank sum test. values for the four example datasets shown in b–e are all within 0.5 units of the means and S.E.

The full data may suggest different conclusions from the summary statistics. These tools are designed to encourage exploration and critical evaluation of the data behind the summary statistics and may be valuable for promoting transparency, reproducibility, and open science in basic biomedical research.įigure 1 Many different distributions can lead to the same bar graph.
A second tool enables authors to create interactive graphics from data obtained with repeated independent experiments ( ). Additional features facilitate visualization of subgroups or clusters of non-independent data. Individual data points may be overlaid on the graphs. This tool allows authors with no programming expertise to create customized interactive graphics, including univariate scatterplots, box plots, and violin plots, for comparing values of a continuous variable across different study groups. This paper introduces a free, web-based tool for creating an interactive alternative to the bar graph ( ). To address this problem, many journals have implemented new policies that require authors to show the data distribution. This presentation is problematic, as many data distributions can lead to the same bar graph, and the actual data may suggest different conclusions from the summary statistics.
