What is the difference between slection crieteria and validity and reliability?
Social and Medical sciences uses these statistical concepts. ideally, we have to measure the same way each time, but intrasubject, interobserver and intraobserver variance occur, so we have to anticipate and evaluate them. In short, it is the repeatability of a measurement, by you, myself and everybody person or instrument. Validity is how much the mean measure that we got is near of the true answer or value. So, an instrument can be reliable but not valid, valid but not reliable, both valid and reliable, nor valid neither reliable. I suggest that you imagine a target: you can aim and 1) always get the center (both valid and reliable) 2) always get the same distant point (reliable but not valid) 3) err much around the true center (valid but not reliable - the mean and median of your arrow's shot will get the center) 4) err much around the another center, false one (nor valid neither reliable) I did not understood exactly what selection criteria have to do with the rest of question, so, left in blank ;-)
Why is it possible to have a reliable measure that is not valid but impossible to have a valid measure that is not reliable?
A reliable measure is consistent and yields consistent results, so it may not be measuring the intended construct accurately (lack validity). On the other hand, a valid measure accurately assesses the intended construct, but it must be consistent and produce stable results (reliable) to ensure that the measurements are dependable and trustworthy.
Is a reliable test necessarily valid?
In my view reliable test is always valid.
Is it possible for an operational definition to be valid but not reliable?
Is it possible for an operational definition to be valid but not reliable
A test may be reliable but not necessarily validIs it possible for a test to be valid but not reliable?
No, for a test to be valid, it must also be reliable. Reliability refers to the consistency of the test results, while validity refers to the accuracy of the test in measuring what it is supposed to measure. A test cannot be valid if it is not reliable.
Does a post dated check comply with the definition of a check and is such a check a valid negotiable instrument?
no it does not complt with the definition of a cheque and its not a valid negotiable instrument
Why is it still necessary to validate research instrument though testing its reliability has been done?
Validation of research instruments is necessary even after testing its reliability because it is the only way to ensure that the results of the study are accurate and meaningful. Validation involves collecting data from research participants examining it and analyzing it to determine if the instrument is measuring what it was designed to measure. Validation is also the only way to ensure that the instrument is reliable and that the results are trustworthy and valid. Here are a few reasons why it is still necessary to validate research instruments even after testing its reliability: Validation helps to ensure that the results of the study are accurate and meaningful. Validation helps to determine if the instrument is measuring what it was designed to measure. Validation ensures that the instrument is reliable and that the results are trustworthy and valid. Validation helps to identify potential sources of bias in the instrument or the data. Validation helps to identify any gaps or weaknesses in the instrument or the data.Validation is an important step in the research process as it helps to ensure that the results of the study are valid and can be trusted. Without validation it is impossible to know if the research instrument is measuring what it was designed to measure and whether the results are reliable and trustworthy.
What is the difference between a valid test and a reliable test?
Reliable indicates that each time the experiment is conducted, the same results are obtained (accuracy). Valid indicates the experiment (or test) has controlled variables and used an appropriate method/model.
Can a test be reliable and yet not valid?
A test may be reliable yet not valid, The results can end up being reliable, in other words certain to have yielded properly based on input. But the results may not be trustworthy.
Sampling techniques can provide statistically reliable and valid survey results except?
when there are errors in sampling design, such as biases in selecting participants or a non-representative sample, which can lead to inaccurate results.
What does a reliable experiment mean?
A reliable experiment is one that can be proven or has been worked out several times giving valid or dependable results.
Give an example of how a test may be reliable but not valid?
A bathroom scale that consistently shows your weight as 10 pounds less than your actual weight, but always produces the same result when you step on it multiple times, can be considered reliable (consistent) but not valid (accurate).
