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.
What does the term utilitarian calculus refers to?
It refers to a system for measuring the total amount of pleasure or pain caused by any action.
What is r2 when measuring the volume of a cylinder?
r2 (r2) refers to the radius of the cylinder squared.
What do you measure grams for?
Grams are a measure of mass. Sometimes people interchange the words 'mass' and 'weight'. But mass refers to the quantity of matter, while weight refers to the force exerted on an object due to gravity. So as long as you have 1g gravitational acceleration exerting on the object, then its mass and weight will be the same. Grams are typically used for measuring mass of small objects. Example: a US nickel has a mass of about 5 grams. (Some people would say it 'weighs' 5 grams).
What is the diameter of the circle 7cm?
It depends on what the 7 cm measure refers to.
What concept refers to measuring exactly what one intends to measure?
repeatability
The cardiovascular suffix ectasis refers to?

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 the validity of a test?
The validity of a test refers to the extent to which it measures what it intends to measure. It assesses if a test is actually capturing the construct or concept it is designed to measure. Validity is essential to ensure that test scores are meaningful and can be generalized to the intended population.

What are validity reliability and practical in the language test?
Validity refers to how well a test measures what it intends to measure. Reliability is the consistency of the test results when the test is administered multiple times. Practicality refers to how feasible and convenient it is to administer and score the test within a given context or setting.
In measuring a curtain does the length or width come first?
Length comes first in measure quadrilaterals.
When measuring the height of a basketball rim do you measure from the top or bottom of the rim to the floor?
The measurement of 10' refers to the distance from the rim to the ground.
Where in the Bible does it tell who was told in a vision to measure the temple in Jerusalem?
It refers to a man with a measuring rod. This man may be representative of an angel, or even a symbol of a pre-incarnate Christ.
What is least count define range of measuring instruments?

When is a study reliable and valid?
A study is considered reliable when it produces consistent results across different trials or measurements, indicating that the findings can be reproduced. Validity, on the other hand, refers to the accuracy of the study in measuring what it intends to measure, ensuring that the conclusions drawn are sound and applicable. A reliable and valid study effectively uses appropriate methodologies, controls for biases, and employs suitable statistical analyses to support its findings. Together, reliability and validity enhance the credibility and generalizability of the research outcomes.
