If you don’t have a zombie apocalypse survival plan, what’s the matter with you?

Any responsible adult interested in keeping his or her loved ones safe when the undead hordes overrun society has already created contingencies for maintaining a food supply, building a zombie-proof shelter, and stocking up on weaponry and other defensive measures for personal protection. One important and obvious factor many long-range planners overlook, however, are the zombies themselves.

Not Redditor zonination, though. In a post in the Data Is Beautiful community, this user enlisted information gathered from other Reddit users in order examine the enemy’s strengths and weaknesses. Here’s how he went about it:

Inspired by this graph, I decided to ping /r/samplesize to see if the Reddit hivemind agreed. Turns out, there’s a slight difference with some movies, and a greater difference with others. Step 1: Gather data on which zombies Reddit wants to rate. This was the first survey I put on /r/samplesize. I instructed them to list as many popular zombie movies, TV shows, books, and video games as they could.

I instructed them to list as many popular zombie movies, TV shows, books, and video games as they could. Step 2: Take the 13 most popular zombies in fiction, and have /r/samplesize rate on speed, strength, and intelligence in a second survey. (All answers were optional, since not everyone has seen everything)

Take the 13 most popular zombies in fiction, and have /r/samplesize rate on speed, strength, and intelligence in a second survey. (All answers were optional, since not everyone has seen everything) Step 3: Some elbow grease with the code. In order to make the survey visually appealing and easy to answer, I had to let Google Forms leave the data in a somewhat messy format. Not to mention I had to perform the analysis on top of that. What I’m trying to say is, this was kinda fun.

This is what the data for the individual shows, movies, and video games—those ranged from The Walking Dead to Zombieland to Resident Evil—looked like once zonination graphed it. The red crosses indicate the average of all the points (the barycenter).

And what conclusions was zonination able to draw?

“It looks like a zombie’s physical abilities scale with its intelligence. There are a lot of smart and strong zombies, but there don’t seem to be (m)any smart and weak zombies.”

“According to this data, if you’re in a TV show, you’re generally regarded as safe from zombies. Especially if that show isn’t Game of Thrones.”

If only [REDACTED] on The Walking Dead had this information a couple weeks back, maybe he’d still be alive today (that is, if this person’s actually really dead).
