Question

A sports psychologist tested whether the number of team wins in the previous season can predict the number of wins in the following season in a sample of 33 teams. Complete the regression table for this hypothetical study. (Round your value for F_obt to two decimal places.)

Source of Variation SS df MS Fobt

Regression 48 1 ? ?

Residual (error) ? ? 7

Total ? ?

Thank you so much!

Answer 1

Source of Variation SS df MS Fobt

Regression 48 1 ? ?

Residual (error) ? ? 7

Total ? ?

MS = SS/df, so MS regression = 48

df for residual = n-2 = 33-2 = 31

SS for residual = df * MS = 31 * 7 = 217

Fobt = MS regression/MS residual = 48/7 = 6.857

SS total = MS regression + MS residual = 48 + 217 = 265

df total = n-1 = 33 -1 = 32 (which also equal df regression (1) + df residual (31)
