Question

I need some assistance on an SPSS assignment. My profession literally never teachers so I'm really lost. All I have a confusing textbook to try to self teach myself.

0.5 pts.) Calculated. Use the provided formula as the two groups have a different sample size. Show me all the steps you follow to get d so that I can give you a partial credit when your answer is incorrect.  

            

d= t ( n1 + n2/ square root of df X square root of n1*n2) (formula isn't appearing for some reason)

(2 pts.) Make a conclusion with APA format (make sure to italicize statistical symbols), including interpretation of d.

Group Statistics

	Female	8	83.1250	15.05644	5.32326

Independent Samples Test
		Levene's Test for Equality of Variances		t-test for Equality of Means
		F	Sig.	t	df	Sig. (2-tailed)	Mean Difference	Std. Error Difference	95% Confidence Interval of the Difference
									Lower	Upper
