Over the past few years more and more schools have been able to gain access to computers. Many have their own terminals, and can work on-line, others send their material to a centre for batch processing. This article looks at some examples of the way such computing facilities can be used in the teaching of statistics. Clearly much more work can be done with interactive programs carried out on-line, but a great deal can be done with off-line facilities. Two difficulties with statistics are that experiments can take a long time and that the resulting computations can become tedious. In both cases the main statistical ideas can get lost in the sheer drudgery involved. One undeniable advantage of a computer is that it does things quickly. It is putting these two facts together that can make computers a useful tool in the teaching of statistics.
