Step 8: Calculate the Mean Squares.

  • Mean Square Between Groups (MSB): MSB=SSBdf1=31.66672=15.83335MSB = \frac{SSB}{df_1} = \frac{31.6667}{2} = 15.83335
  • Mean Square Within Groups (MSW): MSW=SSWdf2=61.700027=2.285185MSW = \frac{SSW}{df_2} = \frac{61.7000}{27} = 2.285185

Step 9: Calculate the F-value.
