Next, change the guessing game in such a way that we are now told what group an observation belongs to. Our best predicted value of Y would then be the mean in that group, yi *. The error we now make becomes the difference between the true value yij and this predicted value. The "penalty" is still the square of the error, that is, (yij yi)2*. The overall "penalty" for doing this for all the observations then becomes the sum of these squares. This is the residual sum of squares as we know it from analysis of variance.
In order to look for answers to this question, we design an experiment with two groups of people. Each group watches a television newscast spliced together from actual stories previously shown on the evening news. One group, known as the experimental group, watches a story on the state of the economy as part of the newscast.
