Question

A researcher wants to investigate different weigh loss options in rats. He divides 24 rats (equal weights) into 3 groups: Control (do not receive any physical exercise), Exercise (receive 6 weeks of physical exercise), and Pill(take diet pill for 6 weeks). He then measures their weight in grams after the 6 week period. 

What is the correct way to report the results in APA style?
 

Question 20 options:

 
F(21) = 518.753, p=.000
 
F(2,21) = 518.753, p<.001
 
F(2,21) = 518.753, p=.000
 
F(21) = 518.753, p<.001
