Answer:
For the following research question, "Is there a significant difference in the overall GPA and GRE scores" based on the SPSS output pictured below?
The correlation between overall GPA and GRE was not significant, r(48) = .035, p = .807, supporting that there is no relation between overall GPA and GRE .
The correlation between overall GPA and GREQuan was significant, r(48) = .427, p = .002, supporting the relation that when overall GPA increases, GREQuan also increases .
The correlation between overall GPA and GREverbal was not significant, r(48) = .124, p = .389, supporting that there is no relation between overall GPA and GREverbal .
Assumptions for correlation:
The data are measured atleast in interval scale.
The correlation coefficient r assumes that the two variables measured
form a bivariate normal distribution population.
The relation between the two variables measured are linear.
There are no outliers in the data.
The assumption of homoscedasticity (same variance or equal scatter).
