A pilot experiment was conducted on 22 right-handedindividuals who were administered a cognitivereflectivity-impulsivity questionnaire, while recording voxel-basedmorphometry (regional gray matter density) in the ventral medialprefrontal cortex.
Based on the experimental design and the kind of data collected,which statistical test(s) should be used to determine whether thereis an association between the cognitive strategy, cognitivereflectivity and the gray matter density of the ventral medialprefrontal cortex? SELECT ALL THAT APPLY!
two sample t-test
z-test
One-way ANOVA
correlation coefficient (r)
t-test of zero linear correlation
