Question

Quizplus · Accepted Answer

If both scales are measuring the same construct (trait anxiety), then they should have a high correlation with each other. This indicates that they are measuring the same thing consistently, which gives us more confidence in the validity of both scales. If they were not correlated, it would suggest that they are measuring different things or that one of the scales is invalid. If they were poorly correlated, it could suggest that there is some overlap in what they measure, but they may not be measuring the same thing with consistency.
