In typical statistical distributions, these are measures that tend to lie close to the centre of the distribution.
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.
Why do we use mean absolute deviation?
It is one of several measures of the spread of data. It is easier to calculate than the standard deviation, which has important statistical properties.

What is the description of validity?
Validity refers to whether a test or assessment accurately measures what it is intended to measure.

Validity is crucial for ensuring that test scores are reliable and can be interpreted correctly.

What is spread?
In a statistical sense, spread, otherwise known as statistical dispersion, is one of various measures of distribution.
Which of these is the best description of validity?
measures what was intended
How are mean median and mode alike?
They are statistical measures of the central tendency of a variable.
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.
