based on the quality of information they has obtained
about that occupation. Hoppock (1967) asserted
occupational information as any and all kinds of
information regarding any position, job or occupation
provided only that the information is potentially useful to a
person who is choosing the occupation. Enhancing this
observation, Oladele (1978) advised Counsellors to
provide the students with accurate, reliable, and
comprehensive facts about occupation or career so that
they can make wise decisions and choices.
5.2 Appraisal Service and Career Choice
From the Analysis in Table 7, the result is significant due to
the fact that the calculated (r) value 0.7466 was greater
than the critical (r) value 0.088 at 0.05 level of significance
with 488 degrees of freedom. The null hypothesis was
rejected in favour of the alternative. The result shows that
appraisal service has relationship with career choice
among students.
This result is in consonance with the confirmation made by
Okafor (1991) when he said, Appraisal is not just for
formality, but for general purpose, such as prediction,
selection, classification, evaluation, and guidance and
counselling. This really shows that appraisal service, if done
properly in school, can give students wider understanding
about their interest, abilities, and aptitudes and therefore
help them choose their career accordingly.
5.3 Vocational Guidance and Career Choice
From the data analysis in Table 8, the result is significant
since the obtained (r) value 0.6656 is greater than the
critical (r) value 0.088 at 0.05 level of significance with 488
degrees of freedom. The null hypothesis was dropped in
favour of the alternative. The significance of this result is that
students who receive vocational guidance have the
benefit of making wise Career Choice.
Ekanem and Eneh (2005) wrote that vocational guidance
assists students to make realistic and appropriate
vocational decisions based on their abilities and interests.
Also Vaughan (1970) in support of this finding stated that
Vocational Guidance is helping people to choose work in
which they will be reasonably contented and successful
within the limits of their abilities.
Multiple Regression was used in testing the hypothesis and
the summary data are shown in Table 11.
Since the computed F (12.00) was greater than the critical
F (2.21) at df of 5.484 and 0.05 level of significance, the null
hypothesis was rejected. Therefore, there exists a joint
effect of the independent variables upon the dependent
variables. The value of R- square of 0.4173 indicated that
the independent variables jointly accounted for 41.52% of
variation of Career Choice among students.
Degree of freedom (df) is the number of values in the final
calculation of a statistic that are free to vary.
Sum of Square (SS) is used to find the function which best fits
from the data.
Mean Squares (MS) are estimates of variance across group.
They are used in analysis of variance and are calculated as
a sum of square divided by appropriate df.
F value is the statistics used to decide whether the model as
a whole has statistically significant predictive capability,
that is, whether, the regression SS is big enough, considering
the number of variables needed to achieve it.
5. Discussion of Findings
5.1 Occupational Information and Career Choice
From the data analysis in Table 6, the result is significant
since the calculated (r) value (0.5726) is greater than the
critical (r) value 0.088 at 0.05 level of significance with 488
degrees of freedom. The null hypothesis was rejected in
favour of the alternative. The significance of the result
means that occupational information has relationship with
the Career Choice among Senior Secondary School
students. This points to the fact that the level of
understanding an individual has about any occupation is
