Data Analysis and Statistical Testing
The research data can be analyzed using various statistical measures and inferring
conclusions from these measures. Figure6.1presents the steps involved in analyzing and
interpreting the research data. The research data should be reduced in a suitable form
before it can be used for further analysis. The statistical techniques can be used to prepro-
cess the attributes (software metrics) so that they can be analyzed and meaningful conclu-
sions can be drawn out of them. After preprocessing of the data, the attributes need to be
reduced so that dimensionality can be reduced and better results can be obtained. ...
