|Test Standardization/Validity/Reliability Metrics|
|Cronbach's Alpha* : 0.71|
*The reliability of a test measures the extent to which the variation in scores is due to true differences between people, or the characteristic being measured, or random measurement error. Reliability is generally assessed on the basis of internal consistency. The most common measure of internal consistency is Cronbach's Alpha. The value indicates the extent to which a test can be considered reliable for a sample of examinees. Any test having a Cronbach's alpha value of more than 0.7 is considered to be having a good internal consistency.
|Content Validity* : The subject matter experts have assessed the test items and found the content to be valid.|
*Validity is the ability of a scale score to reflect what that scale is intended to measure. Kline's (1993) definition is: 'A test is said to be valid if it measures what it claims to measure'. A test has content validity if it measures knowledge of the content domain of which it was designed to measure knowledge. Content validity measures whether the test actually assesses the constructs it is designed for. It is a qualitative measure of validity.
