Initial data analysis (IDA): The first phase in the examination of the data set which comprises  number of informal steps including the following steps

* checking the quality of the data,

* calculating the simple summary statistics and constructing the suitable graphs.

The basic aim is to clarify the structure of the data, attain a simple descriptive sum and perhaps get ideas for the more sophisticated analysis.
