Many people find statistics difficult.
Exploratory data analysis starts from the idea that one should begin by simply getting to know data and making pictures of patterns to be found in it, as opposed to performing sophisticated analyses. The approach concentrates on making sense of data, and on its effective visual presentation. The methods used, though often novel, require little prior knowledge. One of the best is DataDesk which is specially designed to support the exploratory approach. SPSS will also be used.
