on dependent variable (career decision making) as stated in hypotheses one to
three.
Multinomial logistic Regressionwas used because dependent variable had more than two
nominal categories. Like binary logistic regression, multinomial logistic regression uses
maximum likelihood estimation to evaluate the probability of categorical membership. Unlike
other multivariate statistics, Tabanick, Fidell &
Osterlind (2001) argued that multinomial
logistic regression technique has a number of advantages as: i) it is more robust to violations of
assumptions of multivariate normality and equal variance matrices across groups, ii) most
importantly, MLR does not assume a linear relationship between the dependent and independent
variables, iii) independent variables need not be interval, iv) MLR does not require that the
independents be unbounded and lastly v) normally distributed error terms are not assumed
(Tabanick,
et al.,
2001
;
Chan, 2005).
With these advantages, MLR was found suitable to be
used particularly in the field of educational psychology especially for likelihood estimation to
evaluate the probability of categorical membership in the present study. Data analysis was
carried out with aid of both descriptive and inferential analysis (Garson, 2010).
The MLR model assigns a reference category to which all other levels of the dependent variable
are compared as shown in appendix III, part E.The relative risk ratio (rrr) of the alternatives
were estimated simultaneously by comparing the choice of disagree, undecided, agree and
strongly agree with strongly disagree which was the reference category. If the rrr is less than 1,
then the relative risk of choosing the comparison category of student career decision making
compared to strongly disagree is reduced controlling for other variables in the model. If relative
risk ratio is greater than 1, then the relative risk of choosing the comparison category of student
career decision making compared tostrongly disagree is increased controlling for other variables
