In logic‚ it is said that the argument is valid when the conclusion follows deductively from the premises. While of the premises and the conclusion is that they are true or false‚ the arguments are said to be valid or invalid. The validity or invalidity of the argument does not depend on its conclusion

LAQ – Reliability of Memory Discuss‚ with reference to relevant research studies‚ the extent to which memory is reliable. This paper will evaluate the extent to which memory is reliable. While the human ability to have memory is an incredibly complex‚ yet amazing cognitive process‚ recent psychological research demonstrated that memory isn’t an imaginative reconstruction of past events‚ and is therefore not as reliable as previously thought. Memories can be influenced by other factors other than

outcome (increased class participation). Validity is in four types and these are: Conclusion‚ Construct‚ Internal and external validity. Conclusion validity tries to find out the relationship between a program and the observed outcome. For instance‚ a connection between Re-entry policy and increased failure rate in schools. Construct validity looks at the extent to which a test measures what it claims or intend to measure. Internal validity refers to how well an experiment has been done and the extent

has periodic evaluations in order to measure its effectiveness. Accordingly‚ Internal Validity concept is applied in order to score the outcomes. Internal Validity is” the approximate truth about inferences regarding cause-effect or causal relationships” (Trochim‚ 2016). Internal validity is considered at the time of the investigation that measures the results of social programs or interventions. Internal validity observes positive and negative results in order to improve or eliminate services. Therefore

Neil J Salkind defines internal validity as‚ “the quality of an experimental design such that the results obtained are attributed to the manipulation of the independent variable. In other words‚ if what you see is a function of what you did‚ then the experiment has internal validity.” (p. 235). When conducting research with experimental designs‚ researchers usually have two groups to test their experiment. These two groups are called “the experimental group” and the control group”. Experimental designs

There are two main issues to be dealt with in order to answer this question. Identify what is certified to be a valid offer and a valid acceptance.

Assess the Validity of the DTM regarding Global population pressure[15] In this Essay I am going to talk about how valid the Demographic Transition Model is. That means whether it is too predictable ‚ old fashioned or if it doesn’t work with every country due to some Factors being left out. It has to be remembered that the DTM is only a model and cannot predict the future. It does give an indication though of what the future birth and death rates may be for an „underdeveloped“ country‚ together with

Test Validity 1 Introduction Validity is arguably the most important criteria for the quality of a test. The term validity refers to whether or not the test measures what it claims to measure. On a test with high validity the items will be closely linked to the test’s intended focus. For many certification and licensure tests this means that the items will be highly related to a specific job or occupation. If a test has poor validity then it does not measure the job-related content and competencies

Reliability and Trust in Mobile Ad-hoc NETworks (MANET) are considerable due to their applicability in different situations such as military‚ emergency applications or health care applications. Indeed‚ due to absence of a fixed infrastructure and a central controller‚ providing trust and reliability still is challenge in these networks. Since energy is limited and distributed in MANETs‚ trust and reliability providing (is different from wired systems and it must be reasonable and compatible with
