learned the importance of conducting studies that are reliable and valid. Self-reporting scales are useful measuring psychological constructs Purpose of new scale : to generate a new scale and quantify he reliability and validity of that scale We predict that it would gae good internal reliability and high correlation with the big 5 extraversion scale and no correlation with the social desirability scale Method Participants Once the survey was generated each class member was assigned to find 3 random

The Stroop Test has been experimented on numerous times, and because of so, multiple reliability tests have been performed. One such is the test-retest reliability which was given to nearly 30 college students. A total of four tests were given which occurred on two occasions that were spaced by one week. The results produced significant data of coefficients. However, the test-retest

Research in Counseling The purpose of this paper is to know the importance of research in the field of counseling. Address the importance relationship between research and counseling. This paper will also discuss the importance roles and responsibilities of research in the field of counseling. It is important to be aware of the ethical and legal consideration when working with clients. Research is vital in the field of counseling because it provides with proper data on the impact and effectiveness

Terminology Definitions Directions: Define and provide examples of descriptive and inferential statistics and reliability and validity in research. .6 point for each definition and .6 point for each example. 1. Reliability Reliability is defined as “the consistency or constancy of a measuring instrument” (LoBiondo-Wood & Haber, 2014). An example of reliability in research would be weighing a person five times on the same scale and receiving consistent weighs each time. 2. Validity Validity is

his four-stage theory on cognitive development, a widespread theory about the development of the human intelligence. His “stage theory” is a form of discontinuous development, which means that opposed to continuous development, it is not an ongoing progression of gradual changes throughout life; rather certain behaviors and skills occur within distinct stages of life. Piaget was curious as to how knowledge grew as we progressed throughout life. Piaget was also known for his theories on moral development

1. Of the following types of test items: multiple choice, true/false, short answer, long response, or essay questions, which type do you feel provides the most valid and reliable results? I believe that short answers provide the most valid and reliable results. Short answer questions prevent students from guessing and forces them to explain their answers. Students who have to explain their answers gain a better understanding of the material. Short answer questions also provide educators with feedback

Transformational Leadership in Nursing Introduction Transformational Leadership is the moral ability of a person to make sound judgment and wise decision to influence and inspire others to perform the best outcome even in the critical situation. It is the ability to guide others not just in words, but also by example. Nurses are able to cultivate trust and harmony and establish good relationship with their patients and co-workers through effective and constant communication and intervention. They

The patient, Derek, was initially diagnosed with an AC-SC joint separation as a result of a football injury. The diagnosis was then modified to include a periosteal avulsion of the clavicle about four weeks post injury. Derek was immobilized for a total of 8 weeks and was then referred to physical therapy. At the time I evaluated Derek, I was not aware of CPG, how to interpret research, and how to determine if special tests were valid tests. I evaluated and treated Derek based on what I learned

RELIABILITY AND VALIDITY RELIABILITY Reliability is the consistency or repeatability of a measure For example, if I use the measurement twice (e.g. take a test twice) would my scores be the same? Reliability focuses on the consistency of the measurement. If a measurement is reliable you should get the same results if you repeat it. With any measurement the score you get is the observed score. This score is a combination of the true score and error score. Researchers would of course like to eliminate

Selection Methods and Validity Looking back now I would not say this is an unusual selection method. However, at the time I thought this particular selection test was unusual because it was my first time taking a test like this for a job. This method was an integrity test I took years ago for a security position. I believe this selection method was not only valid, but because of the nature of a security position, I believe that an integrity test was an appropriate selection method. The integrity

bad example of this is testing a student with ap The validity of a test is so important because teachers make many decisions based on tests so the accuracy of the assessment matters. Reliability measures the consistency of an assessment. One of the most common forms of reliability is the test-retest reliability. A student takes a tests and then waits an appropriate amount of time and then retakes the assessment the student should score the same. If a children scored high on the previous test, then

Brittney Ingraham BADM 520 Quiz #4 October 24th 2015 1) What are the main criteria for evaluating measure validity? There are 5 different types of validity that are used for evaluating measure. The first criterion is making sure the measure has face validity. Face validity of the measure means that it accurately describes the concept being studied. An easy way to think about this if you make a bakery, you want people to walk in and know it’s a bakery; you cannot sell cars at your bakery and expect

The purpose of this assignment, I will critically discuss and analyse the use of the ABC-E model, when assessing and engaging with a new client. The ABC-E model of emotion is known by a bio-psychosocial model of mental health care which enables a client to understand there autonomic, behavioural and cognitive symptoms in their environment to get a much deeper insight, into how the client may be feeling. Nursing assessments are a key component to mental health nursing care. It is a decision-making

Problem Foundation/Theoretical Orientation/Literature Review The problem with the agency’s data management system, Sigmund, impacts Sovereign’s clinical team. When a new clinician comes on board the only training received for Sigmund are about a dozen videos. These videos are extremely out of date and do not review half of what is essentially needed to properly use Sigmund. Without the clinician receiving a full understanding of Sigmund, the clinician may feel like they are wasting time, and possibly

NEO-PI-R (Benson, 2014). The only novel reliability statistics provided were internal consistency and interrater reliability values (Benson, 2014). Internal consistency for the five domains in the adolescent sample ranged from .87 to .93, and .88 to .95 for the adult sample (Benson, 2014). The facets yielded much lower internal consistency values ranging from .48 to .83 in the adolescents, and .56 to .86 for the adults (Bensons, 2014). Interrater reliability was assessed using cohen’s kappa, in adolescents

3.8. Trustworthiness of the study According to Shenton (as cited in Gabu, 1981, p. 25 & Silverman, 2000, p. 27) the trustworthiness of a qualitative study is often questioned by the positivist perhaps because their opinions of validity and reliability cannot be addressed. Yet, numerous writes on research methods, have verified how qualitative approach can incorporate actions that deals with these issues. Shento (20014) proposed four criteria that he trust should be considered by qualitative academics

First, Gettier Edmund Gettier is an American philosopher who’s well known for his work in the field of epistemology. Gettier is one of the first to challenge the tripartite structure of ‘justified-true-belief’, arguing there are instances in which an individual could have a true belief, this true belief is justified, and given all that, the individual still fails to acquire any knowledge. We’ve all heard the phrase, “Even a broken clock is right twice a day.” Now, imagine by sheer coincidence you
