A series of correlations for these children were computed, including their results in the initial manipulation test and the test carried out later. Divide that by one less than the number of pairs of scores.

The first is because they do not believe that the relationship between these variables is accidental, ie a researcher would apply a survey whose use is known a previously chosen group of people.

This type of survey is used to predict whether or not a product will be successful. The intersection of a row and column shows the correlation between the variable listed for the row and the variable listed for the column.
Likewise, the correlation between the variables can be positive directly proportional or negative inversely proportional. A common fault in statistics is to assume that correlations are significant when they are not, that is, to assume unjustifiably that changes in variables are causally related.
In this way, a researcher may be interested in studying a variable A and its relation and impact on a variable B.
