Collin's "America’s most prolific wall punchers, charted"

Collin gleaned some archival data about ER visits in America from US Consumer Product Safety commission. For each ER visit, there is a brief description of the reason for the visit. Collin queried punching related injuries. See his Method section below describes how he set the parameters for his operationalized variable. With a bit of explaining, you could also describe how Collin took qualitative data (the written description of the injury) and converted it into quantitative data:

Then he made some charts.

The age of wall punchers is right skewed. And probably could be used in a Developmental Psychology class to illustrate poor judgement in adolescents as well as the emergence of the prefrontal cortext/executive thinking skills in one's early 20s.

The author looked at wall punching by month of the year and uncovered a fairly uniform distribution.

 How to use in class:
-Skew
-Taking qualitative data and coding it (here, turning "ER Visit" into "Wall Punch: Yes or No"
-Uniform Distributions
-Method section
-Archival data
-Criteria for operationlizing a variable when coding data
