PSY 654 Study Guide - Internal Consistency
Document Summary
The main reason behind this is because of different view point of each people. This logic is the reason why validity and reliability is important. For example, a related definition to courage can be aggressive. This is usually the case related to actual behaviours in people"s real lives because being courageous means inputting an action that not many people will do such as helping a stranger carry a heavy bag. In order to test for the validity of the measurement i am currently trying to find, first and foremost, it must measure the measurement it was designed to measure. This means that the courage measurement should measure courage. The measurement may give a reliable score but the score may be underestimated due to different interpretation of items. This is exactly the reason why the first question is set as a control question where it will ask for a solid yes or no answer.
