How to choose the appropriate statistical test- Basic guidance for novice researchers

A few days ago, I noticed that this blog had received 30 000 page views last month- a new milestone. As a small gesture of thanks, I am sharing an article that I believe many will find useful.

Background information:

A large proportion of students and novice researchers struggle to determine the appropriate statistical test for a given purpose.

Although there is a plethora of statistical tools available to a statistician, over 60% of the time, knowledge of a hand full of tests is adequate.

However, knowledge of these basic tests is often lacking, as is guidance regarding when to use them. To make matters worse, a biostatistician may not always be available to help.

To address this, I had co-authored an article providing guidance on how to choose the appropriate statistical test using a free program: ‘SOFA’.

The article is written at a basic level, and does not assume any prior statistical knowledge. It provides an algorithm to choose the appropriate test, as well as step-by-step guidance on how to navigate the software.

The article:

Clicking on the top right corner will cause the article to open in a new tab, from where it may be downloaded.

The article was published in an open-access journal, so if you find it useful, please feel free to share with others.

Comments, criticisms, and feedback on the article are most welcome.

Note: Since the publication of the article, SOFA has been updated, so the appearance will be slightly different from that in the article.
