A researcher collected data from male and female Caucasian, African American, and Hispanic graduate students using quantitative measurs 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 finish the dissertation. Dissertation anxiety and number of months to finish a dissertation are not related.
