5 Years of Continuous Blogging, Part 2

In my article about blogging 5 years (part 1), I emphasize quantities of articles over the last five years. This time, I emphasize numbers of words for articles. The images indicate distribution in scatter plots, a line chart, and a box-and-whiskers chart.

The scatter plot for the third year indicates a narrower stream of word counts than the other years. However, it's also the year with the fewest articles. The spread between high and low for word count is as follows:

Sep 2009 to Aug 2010
Sep 2010 to Aug 2011
Sep 2011 to Aug 2012
Sep 2012 to Aug 2013
Sep 2013 to Aug 2014

The line chart shows data points for high, average (mean), median, and low word counts. The box-and-whiskers chart displays the bunching of data. The "whiskers" in the box-and-whiskers graph display the end points to the "box". For each unit:
  • The box represents the middle 50% of the word-count range.
  • The whiskers each depict the other 50%—25% at each end.
  • The line inside the box depicts the median of the word count (spreadsheet-sort of word counts by article and establishing the midpoint).
For each year's period, the line chart numbers for most words, fewest words, and medians coincide with end points and medians in the box-and-whiskers chart. Note that the fifth year "box" (smallest of the five year periods) shows that half the articles fall between approximately 400 and 600 words, with the median around 450.

Some handy resources on graphing, with the first two being the most helpful for me:

For "5 Years Continuous Blogging, Part 3", I will go into more detail about the road I traveled in obtaining and processing my data.
