If other factors are held constant, then how does the size of the standard deviation affect the likelihood of rejecting the null hypothesis and the value for Cohen’s d?

a. A larger standard deviation increases the likelihood of rejecting the null hypothesis and increases the value of Cohen’s d.

b. A larger standard deviation increases the likelihood of rejecting the null hypothesis but decreases the value of Cohen’s d.

c. A larger standard deviation decreases the likelihood of rejecting the null hypothesis but increases the value of Cohen’s d.

d. A larger standard deviation decreases the likelihood of rejecting the null hypothesis and decreases the value of Cohen’s d.
