Psychological assessment measurements are appraised based on two key measurement constructs: reliability and validity. Reliability of an assessment denotes how consistent the test scores are after repeated executions of the assessment. The reliability of an assessment is necessary and is a foundation to build upon for validity. Validity is the second key measurement construct that deals with the degree to which “the evidence exists to support the various inferences, interpretations,…

In order to be sure that the questions I have made up are reliable, I will use Cronbach’s Alpha. I chose this reliability test because I want to be sure that my questions are all asking questions about the same content and none of them are deterring from the main concept of my study and that my questions are measuring the same thing. After I have determined the reliability test, I then need to confirm that my surveys have validity as well. For a validity test, I will use face validity. I am…

Reliability can be measured by test-retest reliability and Internal consistency reliability. Test-retest reliability is a measure of measurement error by repeating the procedure under the same conditions, and in a short period of time. To demonstrate test-retest reliability, we perform the same test to the same test respondents on two separate occasions. Internal consistency reliability is a measure of how well the questionnaires on the test…

Knowing that the minorities usually do not score high can cause anxiety and cause the test taker to score low. The article by Deborah Harmon quotes that o “ African American students ' negative perception of achievement and intelligence tests contribute to lowering test-taking motivation, greater anxiety…

component to literacy. One of the standardized tests developed to measure phonological processing is the Comprehensive Test of Phonological Processing (CTOPP), it was published in 1999. In this paper we will discuss the purpose, normative sample, reliability and validity of the CTOPP. The CTOPP is used to identify individuals ages 5 years to 24 years and 11 months, who are significantly below their peers in important phonological abilities. Due to the wide age range covered…

test administration, respondents are requested to complete basic demographic information on the answer sheet and then are to follow the directions within the test item booklet. The PAI is considered to have a C level qualification, which requires a high level of expertise in test interpretation, and can be purchased by individuals with a doctorate degree in psychology, education, or closely related field with formal training in the ethical administration, scoring and interpretation of clinical…

After identifying the high and low scoring participants, a t-test comparing the means of the high and low scores as well as identifying the significant and non-significant scores was conducted, after identifying this the non-significant scores the scale variable was updated bringing the total from 15 questions to 11. After conducting a discriminative analysis, a Cronbach’s alpha was conducted this refers to a measure used to determine the reliability or consistency of a scale (using and…

Reliability and validity are important factors; they are key factors for having a good test. Reliability is when your test is consistent, whereas validity is the accuracy of your test. You can have a reliable test, yet not valid, but you cannot have a valid test without it being reliable. Here is an example of how reliability and validity work together. Let’s say your scale is 5lbs off, if you weigh yourself it will consistently weigh you 5 lbs off, this is reliability. Validity is your test…

Governess had claimed to see Peter Quint at the window, though Miles cannot see anything; frightening Miles eventually dies of a heart attack and unable to comprehend the accusations the Governess had put upon him. Is the Governess a source of reliability? Or a woman who has gone crazy, and made up these fake illusions of these spirits to justify her actions? That is left to the choice of the reader, of what to think of the Governess. As the reader, I believe the Governess is a mad woman. But…

of sound assessment practice namely reliability, feasibility and educational impact. Reliability Reliability refers to the ‘reproducibility’, ‘repeatability’ or ‘consistency’ of the scores obtained from an assessment (Memon et al, 2010; van der Vleuten et al, 2005). Reliability is generally expressed as a coefficient ranging from 0 (no reliability) to 1 (perfect reliability). Since it is difficult to achieve perfect reliability in any assessment, a reliability coefficient of 0.80 is regarded as…
