F=MSR/MSE=(SSR/(K-1))/(SSE/(N-K))=(SSR/(5-1))/(SSE/(16-5))=5……<1>

by MSF=SSR/(K-1)=10,so, SSR=10(4-1)=40……<2>

by<1><2>得知SSE=22

R²=SSR/SSTO=SSR/(SSR+SSE)=40/(40+22)=0.6451

F=5=[SSR/(5-1)]/[SSE/(16-1-4)]

=> SSE=5.5

=>SST=SSR+SSE=15.5

R^2=SSR/SST=10/15.5=0.645

樓上 F=5=[SSR/(5-1)]/[SSE/(16-1-4)]

應該是F=5=[SSR/(5-1)]/[SSE/(16-4)]
