Abstract
Factor analysis is used largely when the researcher has substantial numbers of variables seemingly measuring similar things. It has proven particularly useful with questionnaires. It examines the pattern of correlations between the variables and calculates new variables, which account for the correlations. In other words, it reduces data involving a number of variables down to a smaller number of factors which encompass the original variables. This paper presents a very brief overview on factor analysis. Although, the factor analysis is complicated and has many variations.
