Document Summary
Calculate the value of sse by pooling the sums of squares of deviations within each of the four samples and compare the answer with the value obtained by subtraction. This is an extension of the pooling procedure used in the two-sample case discussed in section 13. 2. The data on the scores of students who were under study of testing four teaching techniques is available: The following table gives the data with the corresponding column sums and means. As per the definition, sse is sum of squares of deviations of all observations from the corresponding means. Calculate another table by finding the squares of deviations from the corresponding columns means. For example, consider the first observation in first column, 65 and the corresponding column mean is 75. 66667. Similarly, for the first observation in the second column, 75, the corresponding column mean is 78. 42857. Then, calculate the square of deviation from the column mean for the observation:
