To the best of my knowledge (limited) the only smaller package designed for PC's which offers the
possibility for analysing incomplete block designs is INSTAT (and even there I am not sure if that option is
yet available in the presently commercially available version). However it can only be a matter of a short
time before the better PC packages have facilities for analysing incomplete block designs.

Finally, it must be emphasised that it is possible to analyse data from any incomplete block design using
only a small pocket calculator using the method of sweeping. This methci is described in detail in part C.
The only arithmetical operations involved are
 (i) the calculation of means,
 (ii) subtraction, and
 (iii) the summing of squares.

For a large or complex design these operations are repeated many times. If computer facilities are available
then of course they should be used. However sweeping is always a possible method of analysis and should
be understood by all users of analysis of variance, not least because it displays the logic of the analysis
clearly and because it is the principle utilised in the better statistical analysis packages.
