Reliability and Validity Reliability and validity are important with any kind of research. Without them research and their results would be useless. This paper will define the types of reliability and validity as well as give examples of each. Both the data collection methods and the data collection instruments used in human services research will also be given. This paper will also look into why it is important to ensure that data collection methods as well as the instruments are reliable and

Reliability‚ Validity and Accuracy - what do they mean? (To be read in conjunction with an article originally published in Curriculum Support‚ Science‚ 2001 Vol. 6 No. 3) Reliability and validity are two terms that continue to cause problems for teachers and students. Students in Stage 4/5 are required to evaluate evidence for reliability and validity. In Stage 6 they are required to discuss and explain how they would improve the validity and reliability of a first-hand investigation. They could

what is the difference between reliability and validity in what respects are they similar The real difference between reliability and validity is mostly a matter of definition. Reliability estimates the consistency of your measurement‚ or more simply the degree to which an instrument measures the same way each time it is used in under the same conditions with the same subjects. Validity‚ on the other hand‚ involves the degree to which you are measuring what you are supposed to‚ more simply‚ the

In the same way researchers employ vast amount of data collection methods. Additionally‚ it is important to understand how effective these instruments function. Equally important‚ it is necessary to know the magnitude to which the outcomes produces the same findings in the future. Moreover‚ these are reasons researchers study different types of validity and reliability

TEST of Reliability | Application and APPROPRIATENESS | Strengths | Weaknesses | Internal Consistency | This measure of reliability is appropriate when trying to determine the difference in reliability from shortening or lengthening a test (Cohen & Swerdlik‚ 2010). Here I am specifically referring to the Spearman-Brown formula being used to determine internal consistency. A researcher could also use other measures of internal consistency meant for heterogeneous test items‚ such as Inter-item

Challenges to validity and reliability In the based that the research question where answer by the survey show that there was a validity and reliability upon it. The challenges to gain the validity through out the entire research were less. The research question has to be reworded to gain the specific answers the research need from the sample. This also did affect that data from which the sample may be miss lead or confuse by the miss wording. The analysis would have be an error without rewording
