Data management

The data management allows to have a detailed idea about data and possibly add or modify, delete, transform them. It splits in four sections :

• the spreadsheet,
• the qualification ,
• the adjustment,
• the data preparation .

The spreadsheet restores the responses given by respondents in the shape of a table.

The qualification of data allows to spot the particular observations and possibly to modify some data (the non-responses, the poorly documented observations…) in order to establish the global quality of the set of data.

The data adjustment consists in defining weights  to each respondent according to the category it belongs to.

The data preparation allows to transform, combine variables, or create new variables on the basis of personalized calculations. It is also possible to proceed to fusions, imports etc.
