Observational Studies  Not sufficiently training observers and thus obtaining unreliable data.  Using an observation procedure that demands too much of the observer.  Failing to safeguard against the observer’s disturbing or changing the situation being observed Relationship (Correlation) Studies  Assuming that a correlation between pieces of data is proof of a cause-and effect relationship.  Using a sample in correlational research that differs on so many variables that comparisons of groups are not interpretable.  Selecting variables for correlation that have been found unproductive in previous studies.
