Abstract
A statistical teaching apparatus includes a plurality of parallel circuits selectively coupled to an operational amplifier. Each circuit is adapted to receive a component from a population being statistically evaluated. The circuits include amplifier feedback elements arranged to selectively cause the amplifier to produce an output voltage representing the value of a parameter of any selected component or the average parameter value of any selected group of components so as to permit plotting of actual parameter values of a selected subgroup and measuring the average parameter value of that subgroup.
