An estimate of reliability based on the average correlation among items within a test is called:

• Internal consistency reliability

• Alternate forms reliability

• Test-retest reliability

• Split-half reliability

A high level of reliability:

• Ensures high validity

• Has no effect on validity

• Is necessary but not sufficient for validity

• Has a slight effect on validity
