Psychological tests that yield relatively consistent results are said to be?
valid
A psychological tests is said to be valid if it?
A psychological test is said to be valid if it accurately measures what it is intended to measure. This can be determined by comparing the test results to other established measures or criteria to ensure that the test is measuring what it purports to measure.
Why is validity harder to establish and evaluate than reliability?
Validity refers to the accuracy of a measure in assessing what it intends to measure, while reliability refers to the consistency of the measure. Establishing validity involves multiple factors such as construct validity, content validity, and criterion validity, making it more complex than evaluating reliability. It requires more evidence and validation processes to ensure that the measure is actually measuring what it is supposed to.
What is a psycometric test?
A psychometric test is a standardized assessment tool used to measure an individual's psychological attributes, skills, intelligence, or personality traits. These tests are designed to provide reliable and valid results to help assess a person's capabilities, preferences, and behaviors in various contexts such as education, employment, or clinical settings.
What are the characteristics of a psychological test?
Psychological tests are standardized assessments used to measure cognitive abilities, personality traits, emotional functioning, and other psychological constructs. They are carefully designed to be reliable, valid, and consistent in measuring specific aspects of an individual's psychological makeup. Psychological tests are administered and scored in a systematic way to ensure accurate and meaningful results.

A test may be reliable but not necessarily validIs it possible for a test to be valid but not reliable?
A test may be reliable but not valid. A test may not be valid but not reliable. For example, if I use a yard stick that is mislabeled to measure the distance from tee to hole in golf on different length holes, the results will be neither reliable nor valid. If you use the same stick to measure football fields that are the same length the result will reliable (repeatable, consistent) but not valid (wrong numbers of yards). There is no test that is unreliable (repeatable, consistent) and valid (measures what we are looking for).
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.
Is validity is a prerequisite of reliability?
No, validity is not a prerequisite of reliability. Reliability refers to the consistency or stability of a measure, while validity refers to the accuracy of the measure in assessing what it is intended to assess. A measure can be reliable but not valid, meaning it consistently measures something but not necessarily what it is intended to measure.
Is a reliable test necessarily valid?
In my view reliable test is always valid.
How can an instrument be reliable but not valid?
An instrument can be reliable but not valid when it consistently produces the same results under the same conditions, indicating stability and precision, but does not measure what it is intended to measure. For example, a scale that consistently weighs a person's mass the same way might be reliable, but if it is incorrectly calibrated and always adds five pounds, it is not valid for assessing true weight. Thus, while the results are dependable, they do not accurately reflect the intended construct.
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 ;-)

If nothing is impossible then is it possible for something to be impossible?
The question has words which have what I would call (for want of knowledge of a better description) reflective meanings; The words 'nothing' and 'impossible' cannot stand on their own and owe their existence (valid or otherwise) to the words 'thing' and 'possible'. If it were true (as it must, in my opinion be) that all things are possible, it follows that nothing is impossible - but there is no validity in the examination of the validity of the statement 'nothing is impossible' - it simply follows from 'everything is possible'. There is no room to (validly) proceed. Says who? Says I! So are you God? Not yet! (remember I said everything is possible) - Have a good day!
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.
When was the first baby shower held?
This question is impossible to answer since there is no possible valid information regarding it unless you have general knowledge of being at the first baby shower.
Is valid test always valid Why Give example?
A valid test is not always a reliable test. Validity refers to whether a test measures what it claims to measure, while reliability refers to the consistency of test results over time. For example, a test designed to measure mathematical ability may be valid if it accurately assesses math skills, but if the test yields vastly different scores when taken multiple times by the same individual, it lacks reliability. Thus, a test can be valid in content but still unreliable in execution.
