For a two-way classification with p treatments, q blocks and r observations per cell, the degrees of freedom for error and total, respectively, are:
pq(r-1) and pqr-1
In a two-way classification, the degrees of freedom for error is given by \( pq(r-1) \), where \( p \) is the number of treatments, \( q \) is the number of blocks, and \( r \) is the number of observations per cell. The total degrees of freedom is given by \( pqr-1 \), which accounts for the total number of observations minus 1.
