Let’s have a look at the word count plot. The x-axis (horizontal axis) is used for the dates of the blog posts. The y-axis (vertical axis) is for the word counts of the blog posts.
Each dot represents a blog post. Early posts are on the left, recent posts are on the right. Short posts are near the bottom, long posts are higher up.
The black line is a straight linear regression line. The blue curve is a LOESS (local regression) curve, which is a bit more ‘flexible’ than the straight line. You can see that in the first years, posts got longer and longer, while in recent years posts got shorter and shorter.
Cumulative Word Count
Looking at the cumulative word count we see that all Pencil Revolution blog posts together reached a word count of nearly 170,000 by now.
In this chart, the solid line shows the number of cumulative blog posts, as seen in the previous blog post, while the dotted line shows the cumulative word count. The average word count per post is 266, both lines are aligned accordingly. You can see that up to 2011 the posts were longer than the current word count average, while the posts since 2016 have been shorter than the current word count average.
That’s it for now like I said – just a quick blog post to show I’m still here. I hope to post more once work is less busy.
No, I’m not talking about the song by Schradinova.
A New Series
I’m talking about Johnny’s pencil blog – because this is another one of those R / statistics blog posts – as threatened previously. I actually started to work on this in 2015. Originally I wanted to present all the data in one blog post, but because there are old pencil blogs disappearing and new ones appearing regularly this somehow hasn’t worked out yet.
That’s why I’ve now decided to switch to looking at the pencil blogs one by one, always adding to the previous stats and since I haven’t yet figured out a better way of ordering them I decided to start chronologically. The thing is, though, if pencil shops have been around for decades, there may be older pencil blogs I’m not aware of. If you know of any pencil blogs please let me know in the comments, so that I can add it to my list of blogs to be covered. At the moment I have around 30 pencil blogs on my list. Some of the next blogs to be covered will be Pencil Talk, Dave’s Mechanical Pencils and Lexikaliker.
I decided to stick with pencil related blogs, but if there is any interest (usually there isn’t much interest in the statistics related blog posts here) I’m happy to expand to more general stationery blogs.
Also, if the blog owner contacts me to object I will take the blog post about their blog offline, so there is a chance that these stats posts won’t stay.
Here’s the first plot about the oldest pencil blog I know: Pencil Revolution. If there are no objections from Johnny other stats about Pencil Revolution will follow soon.
So far there have been 635 blog posts on Pencil Revolution. Congratulations!
The plot above shows the blog posts over time. Horizontal lines are an indication for periods of inactivity while ‘more vertical’ lines show periods with many blog posts. In the case of Pencil Revolution, you can see that Johnny stopped revolutionising between the Summer of 2006 and the Summer 2010 and between Spring 2011 and Spring 2012 before picking up again. The latest spurt started in the Summer of 2017. I won’t comment further as the graph is fairly straightforward.
Congratulations on more than ten years and more than 600 blog posts.
