Essay on Validity and Reliability Matrix
Internal consistency--The application and appropriateness of internal consistency would be viewed as reliability. Internal consistency describes the continuous results provided in any given test. It guarantees that a range of items measure the singular method giving consistent scores.

These consequences may range from a poor attitude on the part of the test-taker to lawsuits filed by disgruntled parties against a test user and test publishers (Cohen & Swerdlik, 2010).
Content validity—Measures of content validity are most useful in situations a test designer is trying to create test items that match the content of the material being tested (Cohen, Swerdilk, 2010). For example a timed typing test would examine the content area that the course covers. In order for employment test to be content
