Research Scenario: Is there a positive relationship between grit and GPA in high school seniors? A researcher examined this issue by having students beginning their senior year of high school complete a grit inventory using a Likert-based scale (range 1 – 7), where higher numbers indicate more “grit”. GPA was self-reported (scale 0 – 4.0). Enter the data shown here into SPSS to assess whether there is a positive relationship between grit and GPA.

From the above scatter plot between the Grift and GPA, increased the values of Grift increases the corresponding value of GPA and vice-versa. Hence, we can say that these two variable has a positive correlation.

From the output of the SPSS for correlation test, the test statistic value is 0.523 with a positive sign. Also, the p-value for one tail is 0.028 and less than 0.05 level of significance. Hence, we can conclude that these two variables have a significant positive association at the 0.05 level of significance.
