DATA BASE AND RESEARCH METHODOLOGY

Factor Analysis: It is a general name denoting a class of procedures primarily used for data
reduction and summarization. Relationship among set of many interrelated variables are
examined and represented with the help of factor analysis. The approach used in the factor
analysis is “Principle Component Analysis”. In this component analysis, the total variance in
the data is considered. The diagonal of the correlation matrix consists of unities and full
variance is bought in to factor matrix. It determines the minimum number of factors that will
account for maximum variance in the data for use in subsequent multivariate analysis. The
factors are also called principal components. Although the initial or unrotated factor matrix
indicates the relationship between the factors and individual variables, it seldom results in
factors that can be interpreted, because the factors are correlated with many variables. Hence
the variance explained by each factor is redistributed by rotation. The method used for
rotation in this study is “Varimax”. It is a method of factor rotation that minimizes the
numbers of variables with high loading on a factor, thereby enhancing the interpretability of
the factors.

Before the application of factor analysis the reliability of scale items were tested by applying

cronbach’s alpha. The value of all factors ranges between 0.81 to 0.91, indicating the

presence of internal consistency. Further to test the sampling, Kaiser-Meyer-Olin measure of

sampling adequacy is computed which is found to be 0.628. It indicates that sample is good

enough for sampling.

Extraction Method: Principal Component Analysis


It is observed from table that only 5 factors has Eigen value more than one, so accordingly

we preceded with these factors. The total variance explained by factor 1, 2, 3, 4 and 5 is

16.158, 12.031, 11.695, 11.593, 10.593, 62.070 percent of variance, whereas the cumulative

variance explained by all these factors is 62.070 percent and rest of the variance is due to

the factors which are beyond the scope of the study.


Rotation Method: Varimax with Kaiser Normalization. a Rotation converged in 11 iterations.


The table 3 shows that each statement corresponding to the highlighted factor loading is

correlated with the factor corresponding to that factor loading. Higher the factor loading,

stronger is the correlation between the factors and statement. On the basis of rotated

component matrix the factor extraction table has been prepared which is as:

The below table 4 stated factors are in the order of degree of importance i.e. factor 1 is more

important than factor 2; factor 2 is more important than factor 3 and so on. The factor 1 and 2

has 16.158%, and 12.031%of variance which is the highest variance as compared with factor

3, 4, and 5 where % of variance is 11.695, 11.593, and 10.593. Hence it is found that issue of

clearance, age of senior citizen and agriculturist brought under tax shows high variance as

compare to other factors.
