In this assignment, you will discuss ways to gather evidence of a test’s reliability and validity. In a 4 page paper, describe different types of reliability estimates and forms of validity. Then, explain how a test developer or test user could gather evidence of a test’s reliability and validity.
Be sure to address the following in your paper:
-Define the concept of reliability.
-Explain the meaning of a reliability coefficient.
-Explain how a test developer or test user could gather evidence for the test’s reliability using two reliability estimates (i.e., test-retest, parallel-forms, alternative forms, split-half, and internal consistency reliability estimates). For example, how might a test developer who has developed a new psychological test measure test-retest reliability?
-Define the concept of validity.
-Explain the meaning of validation.
-Explain how a test developer or test user could gather evidence for a test’s face validity, content validity, construct validity, and criterion-related validity. For example, how might a test developer who has just developed a new psychological test gather evidence that the test has content validity?
-Cite three or more scholarly sources.

Thank you for the help, I took my time and ordered a 14 days long essay. It came much earlier, around 7 days after I ordered it. Oh, and it was good, of course. I like the writer who did that, will definitely use again.

What I received was great. I forgot to mention in the instructions field that I needed reference page and by default, there was 0 in the number of references. I was surprised to see a full-fledged reference page in my paper with relevant citations. Bravo!

When I first discovered this website I was hesitant on whether they will deliver a plag free paper. The support team reassured me of their plagiarism policy. In deed they kept their word as the paper I got was authentic and plagiarism free.
