Therefore, investigators must pay attention to this issue. Most data errors can hardly be fixed after data are collected and stored on a computer, but there is one exception – missing data. Although

When researcher-computation interaction is involved, outcome from such analysis will no longer be unique. With the same data and analytical method, different results can be generated, each of which is meaningful.

Thus, an X ~ Y relation revealed through bivariate analysis may not be true without further verification by considering factors that may affect the X ~ Y relation, including known and unknown factors.
