Can a source be reliable but not valid?

A reliable measurement is not always valid: the results might be reproducible, but they're not necessarily correct. A valid measurement is generally reliable: if a test produces accurate results, they should be reproducible.

Can something be reliable but not credible?

Something (or someone) is credible when it (or they) can be relied upon to provide accurate information, that can be believed. There is overlap. A person can be reliable, because he or she can be trusted to do something. They can also be credible, when what they say can believed.

Can you have reliability without validity?

"You can have reliability without validity, but you can't have validity without reliability." Reliability measures consistency and stability of a measure. Whereas, validity measures the extent to which a test measure accurately what it is intended to measure. A good measure is both reliable and valid.

Can a test be reliable and yet not valid?

What is the difference between valid and reliable?

Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

What is reliable but not valid research?

A measure can be reliable but not valid, if it is measuring something very consistently but is consistently measuring the wrong construct. Likewise, a measure can be valid but not reliable if it is measuring the right construct, but not doing so in a consistent manner.

How do you know if something is valid and reliable?

What is valid vs reliable in research?

Validity is about what an instrument measures and how well it does so, whereas reliability concerns the truthfulness in the data obtained and the degree to which any measuring tool controls random error.

Which statement most accurately describes a reliable but invalid test?

Answer: The answer is You take a personality test twice and get results that you are extroverted, though you are introverted. Explanation: A reliable but invalid test is one that consistently produces the same results but does not accurately measure what it claims to measure.

Is reliability a guarantee of validity?

Reliability refers to a study's replicability, while validity refers to a study's accuracy. A study can be repeated many times and give the same result each time, and yet the result could be wrong or inaccurate. This study would have high reliability, but low validity; and therefore, conclusions can't be drawn from it.

What makes sources not credible?

Research articles without citations. Materials published over 15 years ago or have theories that are out of date. Individual or business websites. Materials that are published by an entity that may have an ulterior motive.

What makes a source unreliable?

What is an example of both reliable and valid?

For example, if you measure a cup of rice three times, and you get the same result each time, that result is reliable. The validity, on the other hand, refers to the measurement's accuracy. This means that if the standard weight for a cup of rice is 5 grams, and you measure a cup of rice, it should be 5 grams.

When might research offer reliability but not validity?

While reliability is concerned with consistency and reproducibility, validity zeroes in on accuracy and truthfulness. A research tool can be reliable without being valid. For instance, faulty instrument measures might consistently give bad readings (reliable but not valid).

What is reliable but not valid in psychology?

In some cases, a test might be reliable, but not valid. For example, imagine that job applicants are taking a test to determine if they possess a particular personality trait. ​While the test might produce consistent results, it might not actually be measuring the trait that it purports to measure.
