Explanation / Answer

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).
