What is the difference between reliability and validity?
I think that with reliability we mean that the plans tha you propose are based on some spesific and realistic elements. With validity I think that we mean that these elements are true and modern.
Reliability is where if you repeat something and you get around the same answer each time, and validity is if it is true/legit to real life situations. The relationship between the two is that the more tests that are carried out to make it more reliable, the validity will drop because if a study is repeated because it is less true to real life.
What procedures can be followed to ensure the reliability validity currency and accuracy of data information used by an organisation?
Reliability and validity are both important yet different qualities of any measure, including IQ tests. Reliability has a number of different meanings. Reliability might refer to test-retest reliability, which means that you don't get wildly different results each time you take a test. Reliability also refers to the consistency with which observers interpret your results. You would not want two physicians disagreeing about the results of a lab test for cancer. Standardized IQ tests, such…
In sport, suitability is how relevant something is to the chosen sport; reliability refers to how consistent results would be if the test was to be repeatedly taken and validity refers to whether or not the test measures what it claims to. Finally, practicality refers to how appropriate the current environment is for carrying out the test.
One simple argument put forward is that, legal validity of laws presents the fundamental difference between natural and positive law. Natural law theorist argue that the law ought to reflect a higher law and that higher law is morality, to which the law derives its validity, whilst legal positivist believe that the legal validity comes through due process, through acts of Parliament which legislates and makes laws. morality is not a criteria for establishing legal…
Reliability - it has a wide range of results which means it is relaible... Validity- It has many turning points which means more flexion and extension of muscles i necassary this proves its validity because it is giving the appropriate outcome of the time it takes to move in many ways as it isnt a test of speed
Internal validity has to do with the accuracy of the results. Results could be inaccurate if samples are not selected randomly. External validity has to do with the generalizability of the findings to the population. If the sample selected is only Hispanics under the age of 25, then it would be hard to generalize the results to the entire US population.
