The Computer Output

Take-away Points!

1. See how the MS_BG is bigger than MS_WG
   
   
2. F = MS_BG / MS_WG = 43.5/1.042 = 41.76
   
   
3. That's really bigger than 1.0.
   
   
4. Thus the Effect term (a) is really cooking!
   
   
5. Check out "Sig." - the last column. It is .000. That means the probability that there is a difference due to chance (e) is less than .001.
   
   
6. You have a difference or differences somewhere.
