- Scenario:
A researcher collected data from male and female Caucasian, African American, and Hispanic graduate students using quantitative measures of extraversion, academic self-efficacy, dissertation anxiety, and math anxiety, each on a scale of 0 to 100 with higher scores indicating more of the specific latent attribute (e.g., more anxiety). Each participant was also asked if they intended to conduct a qualitative or quantitative dissertation study and how many months they estimated it would take to complete the dissertation.
Note: Items 1 – 4 refer to the scenario.
Select the statistical procedure that would be used to test each of the following null hypotheses:
Dissertation anxiety and number of months to complete a dissertation are not related.
a. Correlation
b. Paired samples t test
c. Analysis of Variance (ANOVA)
d. Multiple linear regression
e. Chi square test of independence
14.29 points
QUESTION 2
- Note: Please refer to the previous scenario to answer this question.
Males and Females do not differ on math anxiety.
a. Correlation
b. Paired samples t test
c. Analysis of Variance (ANOVA)
d. Multiple linear regression
e. Chi square test of independence
14.285 points
QUESTION 3
- Note: Please refer to the previous scenario to answer this question.
There is not an association between ethnicity and intent to conduct a qualitative or quantitative dissertation study.
a. Correlation
b. Paired samples t test
c. Analysis of Variance (ANOVA)
d. Multiple linear regression
e. Chi square test of independence
