Abstract
Correlation and regression are important statistical tools used in the analysis of
relationships between continuous dependent and independent variables. The
understanding of the basic principles and behind the scene calculations will
therefore go a long way in the correct interpretation and application of this statistics.
This study analysed the strength and nature of relationship between test scores and
age, weight and height of students of Veterinary Public Health in a Veterinary
school in Nigeria. Data were collected from the students at the time of writing a
particular test, the data were thereafter used to calculate the Pearson correlation
coefficient and to arrive at the regression equation using established formulae and
calculating machines. Correlation and regression statistical analysis were used to
analyse the data from the study. Other descriptive statistics were done using Fast
Statistics version 2 and IBM SPSS Statistics 19. The three independent variables
were directly related to the students’ test scores. Weight and height had
intermediate relationship while age is weakly related to test scores. The test scores
were predicted for two randomly chosen extreme values of the 3 matrices used for
the study. The predicted test scores indicated that the higher the weight, height and
age of students the higher their test scores. The right application of correlation and
regression could be a veritable tool in Veterinary research to statistically evaluate the relationship between variables and predict dependent variables for the purpose
of preparation, projection and planning.
