Introduction

I found a Kaggle database of a 4967 participant survey of the Fischer Temperament Inventory which consists of 56 questions. While it’s not clear how valid the inventory is, the data collected from such a large number of participants allowed for some light data analysis.

Participants rated themselves (1=strongly disagree… 4=strongly agree) on questions like - I am more creative than most people. - Debating is a good way to match my wits with others.

I examine which questions are correlated by similar ratings. e.g. People who said they agreed with statement X also agreed with statement Y.

While this is not spectacular, it is interesting that this data set does appear to contain “consistent” answers. People did not contradict themselves on the whole… And furthermore, it reminds us that with a good sized data set like this, i.e. with a large set of ‘users’, the answers they give can be aggregated to reveal patterns based on a “correspondence analysis” (I may be deviating from its strict definition).

I used a combination of “contingency tables” and the statistical correlation of the ratings.

The Kaggle database is here.
