This semester I am taking a Digital Humanities course designed and taught by Dr. Jeri Wieringa. Part of this class includes writing blog posts about various topics discussed in class. I have already crafted a few posts (one on accessibility in DH and another assessing and critiquing a DH project) and there will be several more to follow.
Last class, we read and discussed Hadley Wickham‘s “Tidy Data” as a way to re-evaluate the options for organizing and presenting data. For homework, we were tasked with tidying a table from the PEW Research Center on the frequency of prayer. Below is the original table:
According to Wickham’s argument, a table should be made of columns and rows. The columns should consist of a single variable while the rows should be filled with a single observation of what is described. The rest of the table is filled with values that represent the recorded data. Based on Hadley Wickham’s criteria, this Pew research presentation is a bit untidy. What is being described is the percentage of various religious traditions that pray. The frequency of prayer is divided into categories (‘At least daily’, ‘weekly’, ‘monthly’, ‘seldom/never’ ‘don’t know’). These categories represent various observations and as such, should exist in rows, not columns. The column headers should represent the variables being measured.Continue reading “DH Lab 4: Data doesn’t speak for itself”
