> if ... the null hypothesis were true (i.e., social media does not cause harm to teen mental health), then the published studies would just reflect random noise2 and Type I errors (believing something that is false). In that case, we’d see experimental studies producing a wide range of findings, including many that showed benefits to mental health from using social media (or that showed harm to those who go off of social media for a few weeks). Yet there are hardly any such experimental findings.

I recently discovered the tidyplots package in R, and it’s impressive how effortlessly it enables you to create beautiful, publication-ready plots.

The example visualizations shown here were created by the package author, Jan Broder Engler, and are featured on the tidyplots website: https://jbengler.github.io/tidyplots/

Basic boxplots are often not the best way to visualize your data! They can hide important information, such as the distribution of individual data points or group-specific differences.

The attached visual showcases several ways to enhance boxplots.

All of these examples were created using ggplot2 and extensions in R.

The Graphs and Statistics are fascinating in this UN Report. It might provide good exercises for a data or statistcs class: redesign the pie charts, find the original figures and design tables... Just learn from it.. It's a shame the text was garbled when I tried to copy direct from the .pdf..

> ... de Moivre's equation in action. The variation of the mean is inversely proportional to the sample size, so small counties display much greater variation than large counties. A county with, say, 100 inhabitants that has no cancer deaths would be in the lowest category. But if it has 1 cancer death it would be among the highest. Counties like Los Angeles, Cook or Miami-Dade with millions of inhabitants do not bounce around like that.
