If this number is less than or equal to .05, the correlation in significant. If you didn’t want to have to deal with this section of the output window, you could always evaluate the significance of the correlation by using the table from the back of the Welkowitz book.

Notice that as the correlation in our sample of 50 people gets bigger, the probability associated with it gets smaller. So, in a world in which HAPPINESS and INCOME are, in fact, NOT RELATED, we would expect to get a correlation as high as +.20 from a sample of 50 people about 35% of the time. Now, 35% is not all that rare.

A correlation exists between two quantitative variables when one of them is related to the other in some way Chapter 12 : Linear Correlation and Linear Regression Determining whether a linear relationship exists between two quantitative variables, and modeling the relationship with a line, if the linear relationship is significant.

Pearson’s correlation coefficient (denoted by. r). When all data points fall directly on a line with an upward slope r = 1. When all points fall on a trend line with a negative slope r = −1. Less perfect correlations fall between these extremes. Lack of linear correlation is indicted by r ≈ 0. Figure 14.3

The significance test for r evaluates whether there is a linear relationship between the two variables in the population. The appropriate correlation coefficient depends on the scales of measurement of the two variables being correlated.
