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.
