Unfortunately it is very easy to misinterpret and/or mis-use any type of statistics.

People often look at the number while failing to consider how the statistic was calculated or what it truly means.

About Misinterpreting Statistics

Here’s an example:

Statistics show that 45% of the population can’t read the newspaper.

Shocking literacy rates! Or is it? How many included in that statistic were too young to read, didn’t speak English, had some form of disability etc? What percentage of the entire population was sampled, what method was used, did the method bias the result etc?

Using Statistics in Blogging

So where am I going with this? Well bloggers love statistics and they love to know how they rank against other bloggers. Since Technorati authority is no longer reliable bloggers have looked at other options.

So some bloggers are using PostRank. For example, here are the top blogs on education based on their ranking by PostRank. Trouble is bloggers are looking at the statistics and the number 1-10; not considering how it was calculated, how blogs are ranked against each other using PostRank or what these numbers mean.

Effective use of PostRank

Let me be clear! I love PostRank. It is an incredibly valuable tool for quickly analyzing and comparing all of your blog posts in terms of number of:

  1. Comments
  2. Bookmarked (Delicious, diigo etc)
  3. Twittered
  4. Linked to

All of which helps you reflect how the different post types impact how readers engage with the posts. For example, if your aim is a long informative post you would expect few comments but hopefully lots of bookmarking and/or linking. PostRank helps you work out if you achieved this goal.

Misinterpreting PostRank

But if you are using PostRank to compared your blog’s performance against another blog, or identify the best blogs for a topic than you need to look more closely at their statistics.

In particular look at those eye icons that represent views. What do they mean? Well they are the number of your readers that click the post title in the PostRank widget in your sidebar.

Should high clicking on the PostRank widget in a sidebar make a post (and blog) high ranking?

Below is a screenshot from PostRank. The example on the left is a perfect 10 from another blogger (educational) whose rank on that post is entirely based on click on the PostRank widget. While The Edublogger post had high bookmarking, linking and comments.
