r = 
t = 
Decision: reject the null hypothesis or do not reject the null hypothesis 

Key: 

t needed = cut-off score that establishes the region of rejection (also known as the critical value) both groups 

r = score that represents the correlation coefficient 

t = score that determines the significance of the correlation coefficient score
