__________ 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

Answer #1

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.

In a statistics course, a linear regression equation was computed to predict the final-test score from the score on the first quiz. The resulting equation was: ˆy = 25 + 0.84x with a correlation of 0.73 where y is the final test score and x is the score on the first quiz. (a) If Carla scored 82 points on her first quiz, what is the predicted value of her score on the final test? (b) The linear regression line predicted...

A researcher wishes to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used to predict the amount of soil washed away (in kilograms). The researcher measures the amount of soil washed away for various flow rates, and from these data calculates the regression line to be amount of eroded soil = 0.4 + 1.3 (flow rate) What is the slope of the regression line? A. 0.4 B. 1.9 C. X...

A researcher was interested in how students’ Graduate Record Examinations scores (GREQ- Quantitative and GREV-Verbal) predict college students’ graduate school Grade Point Average (GGPA). He collects data from 30 college students. The GRE Quantitative (X1) and GRE Verbal (X2) scores can range from 400-1600 (Note. This is the old GRE score scale). GGPA (Y) can range from 0.00 to 4.00. f. What proportion of variance in graduate grade point average cannot be accounted by the variability in the quantitative GRE...

An educational psychologist studies the effect of frequent testing on retention of class material. The students are randomly assigned to one of two sections of an introductory course. In one section of an introductory course, students are given quizzes each week. A second section of the same course receives only two tests during the semester. At the end of the semester, both sections receive the same final exam. Please choose the statistical test that is most appropriate for this research....

A school administrator wants to test the hypothesis that the grades students anticipate receiving in their classes are related to, and may help to predict, the ratings the students give to their teachers when filling out the teaching evaluations. Each of 12 randomly selected students indicated the grade he or she anticipated receiving in a course and rated the instructor of the course. The anticipated grades were transformed into numerical scores as follows: A = 4, B = 3, C...
