This example deals with only items # 3 and # 8 of the questionnaire. Those questions were "In the past week how often have you felt sad or depressed?" and "In the past week how often have you felt tense?" and are labeled as DEPRES and TENSE respectively. A discussion of the correlation between responses to these two items (items 3 and 8 on the questionnaire) follows.

We will now present this data in the same way as the more limited data was presented in chapter 2. So that all of the formulae are the same as those presented in chapter 2 you're not learning a new set. This is a more alive example and goes through the same process as in the previous chapter. The variable TENSE is labeled as the X variable (predictor or independent variable) and DEPRES as the Y variable (criterion or dependent variable). First the data will be presented and the SPSS syntax files to compute it will be given.

Table 2-3. Rows A through F are either mathematical notation or verbal description of mathematical calculations of the numbers in the column. Rows 1 through 20 are associated numbers involved the calculation. Row G is the sum of the numbers in the column while row H is the mean for the column. Row I is the usual verbal description of the sum in the column and row J is an abbreviation of that description.

In the example below when there are scores for all 20 cases are individually computed only the first 4 will be given (this occurs with observation, little x, Y' and SSE).
