Recommended: Characteristics of construct validity
External, Internal, and Construct Validity
Introduction
This paper will compare and contrast the characteristics of internal, external, and construct validity. Also discussed will be the threats to external and construct validity. In addition, based on the envisioned research, this paper will discuss the impact of validity issues on this research.
Compare and contrast the characteristics of internal and external construct validity
Construct validity is determined by whether an instrument measures what it says that it will measure. There are several indicators of construct validity, according to Cozby (2012), including face validity, content validity, predictive validity, concurrent validity, convergent validity, and discriminant validity. What all of these types of validity appear to have in common is the fact that they all allow for comparing a variable that is being measured against something else in the universe. If the two items match, you have construct validity.
Another example of construct validity is whether the Theory of Reasoned Action, which provides an explana...
One of the major criticisms of Kellys Personal Construct Theory is that he finds it hard to explain why constructs are laid down in the first place and why one would rigourously defend the threat to a core construct. What kick starts the Construct system into defending itself when motivation is clearly and explicitly lacking in his theory?
The concept of construal helps us understand what motivates human behaviors, and it shows us the variation in comprehension of the social world. It also brings to light the importance of situational influence and subjective properties, which, in turn, helps us understand the fundamental attribution error, or the tendency to explain behaviors in terms of personality traits instead of situational.
Bandura’s social cognitive theory (SCT) was the foundation for models of behaviour. Bandura (1977, 1986) proposed that behaviour is determined by incentives, expectations and social cognitions. He asserts that behaviour is determined by the expectancy that a behaviour may be hazardous (Situation outcome expectancies), that a behaviour can decrease the associated health-risk (Outcome expectancies) and that the individual is competent enough to undertake the behaviour (Self-efficacy expectancies). SCT also proposes that a behaviour is controlled by its
If the PANAS added either more terms or more questions, without repetition, there is little doubt that both reliability and validity could increase. Each construct could include two questions to reduce random response errors or gather more information.
the relationship between an assessment and the construct (“personal psychological characteristic that cannot be observed directly but which is assumed to exist”) it purports to measure; and the interpretations of the test scores based on the assessment- the so-called validity argument.
A Multinational Corporation (MNC) can be defined as “a single entity that controls and manages group of goal-disparate and geographically dispersed productive subsidiaries” (Triandis and Wasti, 2008, p. 2). Multinational corporations are entities that make Foreign Direct Investment (FDI) and produce added value in countries other than the country in which they are headquartered. One of the key objectives of the MNC is to obtain capital where is it cheapest and to invest FDI and undertake production in areas that yield the highest rates of return (De Beule and Van Den Bulcke, 2009). However, many theories have been advanced to account for the decision-making process that MNCs undertake in relation to FDI. The purpose of this paper is to explain the two main theories – internalization theory and OLI eclectic paradigm theory – and to critique these in relation to some of the other conceptual models that have been advocated.
However, both characteristics of reliability and validity are important and can be used in many studies, such as the self-rating and other- ratings of daily behavior. Reliability refers to the internal consistency, inter-rater reliability, test-retest, and standardized scoring. In other words reliability means that study scores have to be constant with repeatability of the findings. Validity also refers to convergent validity, discriminant validity, and predictive validity. Validity refers to the reliability or credibility of the research. If the findings in a study, reliability and validity are valid they must be reliable.
8. Validity - Validity is the degree to which a test measures what it is supposed to measure.
Knowledge can be achieved either through the justification of a true belief or for the substantive externalist, through a “natural or law like connection between the truth of what is believed and the person’s belief” (P.135). Suppose a man named George was implanted with a chip at birth, which causes him to utter the time in a rare Russian dialect. His girlfriend Irina, who happens to speak the same Russian dialect, realizes that every time she taps his shoulder, he tells her the time and he is always right. She knows that he is right because she checks her watch. Because she thinks this is cute, she never tells him what it is that he is saying. One day, Irina’s watch breaks but instead of getting it fixed, she just taps George on the shoulder whenever she needs to ask for the time.
Validity is how well a test or measurement tool measures what it purports to measure. Traditionally validity is conceptualized into three categories content validity, construct validity, and criterion-related validity (Cohen, 2013). Content validity measures the validity based on an evaluation
Likewise, in order to validate construct validity, Malhotra et al. (2012) recommends that in conducting research, researchers should use multi versus single-item scales to validate data from experiments, depending upon the complexity of the experiment. Malhotra et al. (2012) also recommends using a step-by-step approach ...
A researcher uses an experiment to scientifically test out a hypothesis. In an experiment there are many different factors that are involved. There is the independent variable, which is the cause, it is the one that is being manipulated, and the dependent variable, which is the effect, is the response. When conducting a experiment it is important to make sure that the only thing than can affect the dependent variable is the independent variable. This is known as internal validity. Using random assignment to separate the participants into groups helps eliminate any outside factors, and creates an equal chance for all participants to be apart of the experimental conditions. There are many pros and cons to this type of method. The experimental method creates a strong control of the variables involved in the experiment, which allows an easier determination on cause and effect. If needed, it is fairly easy to replicate an experiment and is less time consuming than other research methods. However there are many downfalls as well. When conducting an experiment the setting of where the experiment is taking place is more artificial which may cause certain behaviors that wouldn’t occur in real life. This is known as external validity, which is the measure of how much the results of a study can be generalized and used in different situations, and people. To improve external validity cover stories are created when conducting experiments so the participants are not aware of what is really going on, or experiments are done in a natural setting as opposed to in a laboratory. However, this creates less control over confounding variables that can affect the experiment, which can create bias results (Aronson,
The term constructivism has been used to explain everything from school reform to teaching styles, and most importantly related to a learning theory. As you can imagine the term Constructivism has the potential to develop many misconceptions since it lacks a universal definition. “Constructivism is an important theory of learning that is used to guide the development of new teaching methods”(Baviskar, Hartle & Whitney, 2009, p.541). The framework of constructivism is built upon the understanding that “learning is an active process that is student centered in the sense that, with the teachers help, learners select and transform information, construct hypothesis’, and make decisions”(Chrenka, 2001, p.694). It is important to understand that when speaking about constructivism we are referring to a learning theory not teach...

Organisation is the most important element in management. Any organization is located and operated in the environment. Every action of all organizations is possible only if it allows its realization. The internal environment is the source of its vitality. It involves the capacity needed for the functioning of the organization, but at the same time can be a source of problems and even her death of the organisation. The external environment is the source that supply organization resources. The organization is in constant exchange with the external environment consequently it provides itself with survival. The main objective of this work is to consider elements of the internal and external environment of the organization which are in a constant
