Fourteen medical students in their last year of training are asked to make diagnostic decisions under three conditions: alone, with two senior doctors present and in a simulation of a chaotic emergency department. Twelve first year medical students are also asked to complete the same task conditions.
-6) The between groups error df will be:
A) 25
B) 24
C) 26
D) 77

Question

The between groups error df will be equal to the number of participants minus the number of conditions, so for the 14 last year medical students, the error df will be 14-3=11 and for the 12 first year medical students, the error df will be 12-3=9. The total between groups error df will be 11+9=20. Therefore, the total degrees of freedom for error will be n-1, where n is the total number of participants, which is 26. Subtracting 20 from 26 gives us 6, which is the between groups error df. Therefore, the answer is B.
