Over the past few days, some readers have encountered a random error-free error. This issue occurs due to a number of factors. Let’s discuss this below. Reliability is the degree to which a measurement is free from random error.
Reliability and validity are probably two desirable characteristics of any voluminous procedure or instrument. There should not be a perfect relevance of reliability oralidity. Even measurements that we consider the best always have a source of error.
Reliability Is The Degree To Which “a Large Experiment, Test, Or Other Measurement Method Gives The Same Results When Used Together”2. The Tendency Towards Consistency, Manifested In Repeated Measurements, Is Its Reliability. So Even Mrs. Jones, Holding The Pressure, Gave Three Different Readings From The Nurse, Your Clinical Student, And You Nearby. Is One Sky High And The Other Low. There Is A Balance Between Reliability And Strategic Values.
True Is The Extent To Which Measurements Reflect What They Claim To Be Measuring. The Use Of A Blood Pressure Cuff Is Seriously Considered Acceptable Because It Is Likely To Measure Blood Pressure And Not Anything Else. Using An Ophthalmoscope To Measure Blood Pressure Is Not Really A Valid Method.
How can I determine if my measurements are reliable and valid?
To determine if IAre your measurements reliable and valid, you need to find the sources of error. There are two types of noise that can affect your measurements: known non-random and.
Random errors consist of random factors affecting our own measurements. The more precise the error, the less reliable the output.
