Reliability in a research paper

This process yields so many sources and information that becomes difficult for you to analyze and decide which ones are better. Use only two criteria to decide what sources you have to keep and what you do not need in your research paper.

Reliability in a research paper

Download this Research Paper in word format. Administering the tests developed and formulated for the nursing-based curriculum entails providing reliable test items. Reliability is important because it helps counteract human error both on the part of the student taking the test and the person grading the test.

Students sometimes randomly miss a question they really knew the answer to or sometimes get an answer correct just by guessing" KU, By increasing the reliability of the test items, the quality remains consistent in the test and offers a superior level of testing that avoids the pitfalls of unavoidable human error.

For instance, there are different ways to construct a test. With each different way, there are various measuring methods to help provide reliable outcomes. Essay questions and multiple-choice questions can contain qualitative or quantitative data that are measured differently.

Multiple-choice questions are measured quantitatively and some ways to measure such data is the Kuder-Richardson, the alpha coefficient, or the split-half. The Kuder and Richardson Formula 20 test allows the person to check for "internal consistency of measurements with dichotomous choices" Real Statistics, It is equal to the aforementioned split half methodology in "all combinations of questions" Real Statistics,remaining applicable whether the question is wrong or right.

With values ranging from 0 to 1 and reliability is indicated from a high value, an excess of. The alpha coefficient goes by a different name. It is Cronbach's alpha and is a measure of how closely associated a set of items exist as a group internal consistency.

If there is a 'high' value for alpha this does not suggest a unidimensional measure. If there is a desire to offer evidence for a unidimensional scale, further analyses may be done.

To check dimensionality, a common method is exploratory factor analysis. Split-half reliability is another measure of consistency and is similar to the Kuder and Richardson Formula 20 test, except in this test, the scores are split into two parts that are then compared with one another.

If the results remain consistent, the assumptions are it is highly likely measuring the same thing. This test does not measure validity.

These methods for testing reliability allow the multiple-choice portion of an exam to be properly analyzed and create certainty over the consistency of the test items, forming the basis of a superior quality test.

Essay questions have a different method of analysis since that data is qualitative. Qualitative data is generally analyzed using an analytic rubric.

The Concept of Validity in Qualitative Research - Reading Craze

Analytic rubrics are seen often in paper assignments where students receive a table featuring a vertical and horizontal list of categories. The scale is usually from with a score at the end.

This is for the horizontal categories with 1 being the worst and 5 being exemplary.

The vertical aspect contains what is being graded such as presentation, grammarand so forth. These categories relate to the instructions of an assignment and how well the student follows said instructions. It is a reliable measure to take because it provides a detailed explanation of why a student receives the score they do, avoiding any misconceptions.This white paper describes principles and strategies used successfully in other industries to help evaluate, calculate, and improve the overall reliability of complex systems, and explains the application of reliability principles to health care.

Reliability and Validity Research Paper  Reliability and validity are essential in terms of observation and measurement as it relates to human services research. In order to ensure this particular research has legitimacy it is vital that testing and research is consistent and specific.

This paper discussed how the applying of Rasch Model in validity and reliability of research instruments. Three sets of research instruments were developed in this study. Therefore, reliability, validity and triangulation, if they are relevant research concepts, particularly from a qualitative point of view, have to be redefined in order to reflect the multiple ways of establishing truth.

This paper reports a new tool for assessing the reliability of text interpretations heretofore unavailable to qualitative research.

Ensuring the Validity of Research

It responds to a combination of two challenges, the problem of assessing the reliability of. Reliability is a necessary ingredient for determining the overall validity of a scientific experiment and enhancing the strength of the results.

Debate between social and pure scientists, concerning reliability, is robust and ongoing.
