Question 1
 
    We reject H0 for the independent samples t test if the obtained values of t
                       
 
    are larger in absolute value than the critical values.
                       
 
    are smaller in absolute value than the critical values.
                       
 
    are the same in absolute value than the critical values.
 
 
Question 2
 
    Based on these results, t (92) = -.67, p = .41, d = -.10. The math scores of males (M = 31.54, SD = 5.16, n = 29) on and females were compared (M = 32.46, SD = 4.96, n = 65). What can be concluded based on these results?
                       
 
    Males (M = 31.54, SD = 5.16, n = 29) on average score statistically significantly higher than females (M = 32.46, SD = 4.96, n = 65) in terms of math achievement.
                       
 
    Males (M = 31.54, SD = 5.16, n = 29) on average do not statistically significantly differ from females (M = 32.46, SD = 4.96, n = 65) in terms of math achievement
                       
 
    Males (M = 31.54, SD = 5.16, n = 29) on average score statistically significantly lower than females (M = 32.46, SD = 4.96, n = 65) in terms of math achievement.
 
 
Question 3
 
    Based on these results, t(90)= 3.66, p= .04, η2 = .25, what can the educational researcher say about the null hypothesis?
                       
 
    Reject the null hypothesis
                       
 
    Fail to reject the null hypothesis
 
 
Question 4
 
    The F (Levene) test on the SPSS output tests for what assumption?
                       
 
    The normality assumption
                       
 
    The homogeneity of variance assumption
                       
 
    The assumption of extreme outliers
