Question

Imagine you are doing a Related-Samples t-test, and you are on Step Three of the hypothesis test.  The sample of difference scores that you calculated is -1, -1, -3, +2, 0, -4.  What is the correct t-obtained? 

NOTE: The answer options also show many numbers that you calculate as part of the WORK for getting the t-obtained. 

VERY IMPORTANT HINT: The SS of these difference scores is 22.83.


A. MD (mean of D’s) = -1.67

SD (standard deviation of D’s) = 3.21

SMD (standard error) = 1.86

t-obt = -0.90

 

B. MD (mean of D’s) = -2.00

SD (standard deviation of D’s) = 2.16

SMD (standard error) = 1.08

t-obt = -1.85

 

C. MD (mean of D’s) = -1.17

SD (standard deviation of D’s) = 2.14

SMD (standard error) = 0.87

t-obt = -1.34

 

D. MD (mean of D’s) = -2.20

SD (standard deviation of D’s) = 3.35

SMD (standard error) = 1.50

t-obt = -1.47Thank
