__________ A researcher hypothesized that the score from the GRE
test is positively associated with the final-statistics course
grade. The data was collected from 80 new nursing students on their
GRE score and final-statistics grade.
Research question: Is there any relationship/association between
the GRE score and final-exam score in statistics course among
nursing students? Please indicate which statistical test
should be used below.
a. Independent t-test
b. Dependent t-test
c. One-way ANOVA
d. Two-way ANOVA
e. RM-ANOVA
f. Pearson’s Correlation
g. Multiple Linear Regression
f. Pearson’s Correlation
Explanation:
Here, we have to use t test for the population correlation coefficient.
The null and alternative hypotheses for this test are given as below:
Null hypothesis: H0: There is no relationship between the GRE score and final-exam score in statistics course among nursing students.
Alternative hypothesis: Ha: There is a positive relationship between the GRE score and final-exam score in statistics course among nursing students.
H0: ρ = 0
Ha: ρ > 0
This is an upper tailed or right tailed test.
