1. Two ways to establish the reliability of a test are test-retest and parallel-forms. Test-retest establishes reliability by having participants retake the same test at different points of time (Salkind, 2012). For example, a 3rd grade English class takes a Fry Words test at the beginning of the school year and retakes the same test at the end of the school year. Test-retest yields the best results when a researcher considers both the length of time between each test and how they intend to use…

The second is Reactive Anger (RA), which refers to the type of anger that occurs as an immediate response to a stimulus. Finally, the instrument measures Anger Control (AC), which refers to the subject’s anger management ability. These three scales come together to form a Total Anger score, which is “a general index of anger expression.” The AARS is a tool for me to choose it was designed from a cognitive-behavioral perspective (Henington, 2001). It is also a reasonable choice for Jeffery’s case…

Many arguments can and have been made in favor of and against proficiency, or standardized tests. While to a certain, albeit small degree, I can understand how standardized testing can be beneficial to assess students and teachers, and potentially halt social promotion, the practice of allowing students to advance from grade to grade whether or not they have met the academic standards of their grade level. I do not agree that proficiency tests are the answer for our children’s education.…

Probability: Coin Tossing Project Student’s name: Institutional Affiliation: Introduction Probability is very essential in determining the likeliness with which an event may or may not take place. It plays an important role in various fields but has been implemented widely in gambling. The con tossing project is aimed at determining the highest level of success with which a particular event carried out multiple times would bare. The guesses were aimed at setting…

People have different understandings and definitions of what an outlier is. According to the dictionary, outlier means a person or thing situated away or detached from the main body or system. If you ask me, an outlier is someone who figures out the solution to a problem that someone else couldn’t. Malcolm Gladwell’s definition of an outlier is a person that works hard to be successful and its intelligence is far above than an average person. In The Outliers, Gladwell shows us his beliefs by…

Standardized testing has been a method that has been implemented into the school systems in order of them to be able to measure a student 's achievement. While in some cases the students come out on top, but more often than not a lot of students are left behind due to their inability of the attaining their school systems standards. The school system 's ability to measure students achievements needs to change in order for the school systems to be more successful. For a long time the…

While our children only make up a fraction of our population, they make up a %100 of our future. The future of this country is in their hands. Some will go on to be doctors or lawyers, some will go other routes such as mechanics and engineers, but they will all start together, in one room, learning the same thing, in the exact same way in public schools. Every single child is gifted early education, but at what cost? Free, or so one would assume. Yet, how free are our children when they are…

To determine a person’s needs psychologically a psychologist must first learn about the patient. Many tools are used to assist psychologist in diagnosing patients. These include clinical interviews, assessments, and even neurological tests. These tests may give us sufficient information about a patient as long as it has reliability, and validity. The personality assessments vary in different fields from introvert vs. extrovert to rough vs. mindfulness. The first test assessed whether I was an…

My dependent variable will be their perception of their latest relationship. To measure this, I will be using a Guttmann scale. This will enable me to incorporate both a dichotomous scale and a Likert scale. A dichotomous scale is when a question has two possible responses. A Likert scale is a type of rating scale that measures how someone feels about a certain topic containing degrees of feeling. With multiple Likert questions in a survey Cronbach’s alpha helps measure its reliability.…

Every year students are forced to take standardized test while they are in school to test their knowledge and their growth year to year, but do these tests truly test a student’s knowledge and growth? No, while sometimes they accurately measure a student’s knowledge and growth, often it does not. The way to make this more accurate is to not necessarily get rid of standardize test but make them to where they are helpful to the students and place them in classes with students that have similar…
