Reliability of Confirmatory Exploratory Data Analysis

Scientific studies using confirmatory exploratory data analysis limiting tests of significance to calculation of P values have come under increasing criticism. It has been found that it has been impossible to replicate many such studies and their conclusions can therefore not be considered true. So how reliable are the results of confirmatory exploratory data analytic studies for supporting decisions and actions?

Reliability of Basic Exploratory Data Analysis – 2

In a post written the 27th of October on basic exploratory data analysis I expressed concern about the reliability of its results for supporting decisions and actions if improperly applied.

If improperly done basic exploratory data analysis reminds me of Munchhausen’s Journey to the Moon. I am also reminded of Buddha’s parable about blind Indians trying to describe an elephant.

Lately I have been wondering about the reliability of the results of the various types of exploratory data analysis for supporting decisions and actions. How confident can we be in the decisions and actions based on these results and how willing are we to take responsibility for the risks associated with them.

 I have composed a page with the same name as the post where I discuss these questions.

Perhaps I should have named this post and its associated page:

From World Development Indicators to Tableau

Some of my data analytic projects require data from The World Bank’s “World Development Indicators”. In order to simplify the process of getting the data from WDI to Tableau I have developed a procedure to execute the process.

This procedure is described in the following related set of pages:
