Question

Quizplus · Accepted Answer

Increasing the number of items within the measurement scale can improve the reliability of the scale because it allows for a more comprehensive and representative assessment of the construct being measured. It helps to reduce the effects of random measurement error and increase the overall consistency of the scale. However, it is important to ensure that the items are relevant and appropriate for the construct being measured.
