Question

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.

Grit	GPA
6.5	4.0
4.0	3.1
3.7	2.7
5.8	3.5
4.7	3.1
5.5	3.3
3.9	2.7
1.1	2.8
3.5	3.1
2.7	2.6
5.1	3.8
3.2	2.2
5.6	2.8
6.1	2.5

1. Paste relevant SPSS output.  (2 pts)

2.     Create an appropriate graph to display this data. (2 pts)

3.     Write an APA-style Results section based on your analysis. All homework “Results sections” should follow the examples provided in the presentations and textbooks. They should include the statistical statement within a complete sentence that mentions the type of test conducted, whether the test was significant, and if relevant, coefficient of determination and its interpretation. Don’t forget to include a decision about the null hypothesis. (3 pts)

Answer 1

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.

Correlations
		Grift	GPA
Grift	Pearson Correlation	1	.523*
Sig. (1-tailed)		.028
N	14	14
GPA	Pearson Correlation	.523*	1
Sig. (1-tailed)	.028
N	14	14

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.
