There is none. If an accurate measure was possible then statistical techniques would not be required. A maximum likelihood estimate is probably better than other statistical estimates.

In the language of assessment a test that measures what an assessor intended it to measure is what?

In the language of assessment, a test that measures what an assessor intended it to measure is referred to as having high validity. Validity ensures that the test accurately reflects the specific skills, knowledge, or constructs it aims to evaluate. This can encompass various types, such as content validity, construct validity, and criterion-related validity, each serving to confirm the test's relevance and effectiveness in assessing the intended outcomes.


What is the degree at which a test measures what it is intended to measure?

validity


Why are the mean mode and median considered measures of central tendency?

In typical statistical distributions, these are measures that tend to lie close to the centre of the distribution.


Why valid measure is always reliable?

A valid measure accurately captures what it intends to assess, meaning it reflects the true construct or phenomenon. Because a valid measure consistently produces accurate results, it inherently exhibits reliability, as reliability refers to the consistency and stability of measurements over time. However, not all reliable measures are valid, as they may yield consistent results without accurately measuring the intended construct. Thus, while all valid measures are reliable, the reverse is not necessarily true.


How does mean median and mode apply in life?

They are statistical measures that are used, when appropriate, to summarise the central tendency of a set of data. That is, given a number of observations, these measures can give an indication of the value near which they all are.

Indicates the ability of a test to measure what it actually is supposed to measure?

This is known as the validity of a test. It is the degree to which a test accurately measures what it claims to measure. High validity indicates that the test is accurately assessing the intended construct or concept.

What is the description of validity?

Validity refers to whether a test or assessment accurately measures what it is intended to measure. It assesses the extent to which a test provides meaningful and useful information about the construct it is designed to measure. Validity is crucial for ensuring that test scores are reliable and can be interpreted correctly.

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.
