Answer 1

Cronbach's alpha is a statistical measure that assesses internal consistency in research or test items. It determines the extent to which items in a survey or test are measuring the same underlying construct.

Step-by-step explanation:

Cronbach's alpha (coefficient alpha) is a statistical measure that assesses internal consistency in research or test items. It determines the extent to which items in a survey or test are measuring the same underlying construct. For example, if you have a questionnaire with multiple items assessing the same concept, Cronbach's alpha can measure how well those items are related to each other. It is commonly used in fields such as psychology, education, and social sciences.
