of knowledge about its cause system as well as ''contextual'' information. EDA aims at letting the data itself influence the process of suggesting hypotheses instead of only using it to evaluate given ''(a priori)'' hypotheses.<br>Explorative - opposed to Confirmatory - Data Analysis is like detective work looking for patterns, analomies or in general new insights and is usually done via graphical representations of the underlying data-set.}}

	{{Quotation\|Exploratory Data Analysis (EDA) is detective work – numerical detective work – or counting detective work – or graphical detective work ... unless exploratory data analysis uncovers indications, usually quantitative ones, there is likely to be nothing for confirmatory data analysis to consider ...

about its cause system as well as ''contextual'' information. EDA aims at letting the data itself influence the process of suggesting hypotheses instead of only using it to evaluate given ''(a priori)'' hypotheses.<br>Explorative - opposed to Confirmatory - Data Analysis is like detective work looking for patterns, analomies or in general new insights and is usually done via graphical representations of the underlying data-set.}}

	{{Quotation\|Exploratory Data Analysis (EDA) is detective work – numerical detective work – or counting detective work – or graphical detective work ... unless exploratory data analysis uncovers indications, usually quantitative ones, there is likely to be nothing for confirmatory data analysis to consider ... [it] can never be the whole story, but nothing else can serve as the foundation stone - as the first step. \|[Tukey, 1977, p. 1-3]}}		{{Quotation\|Exploratory Data Analysis (EDA) is detective work – numerical detective work – or counting detective work – or graphical detective work ... unless exploratory data analysis uncovers indications, usually quantitative ones, there is likely to be nothing for confirmatory data analysis to consider ...

to analyze data when there is only a low level of knowledge about its cause system as well as ''contextual'' information. EDA aims at letting the data itself influence the process of suggesting hypotheses instead of only using it to evaluate given ''(a priori)'' hypotheses.<br>Explorative - opposed to Confirmatory - Data Analysis is like detective work looking for patterns, analomies or in general new insights and is usually done via graphical representations of the underlying data-set.}}
