Question

What are the differences between the objectives of data summarization and data reduction

Answer 1

Data reduction is the transformation of numerical or alphabetical digital information derived empirically or experimentally into a corrected, ordered, and simplified form. The basic concept is the reduction of multitudinous amounts of data down to the meaningful parts

The basic difference between the objectives of data summarization and data reduction depends upon the ultimate research question. In data summarization the ultimate research question may be to better understand the interrelationship among the variables.
