The correct answer is validity
The perfect validity signals that there is no measurement error, that is, that “the differences observed in the measurement reflect the real differences between the objects (or individuals)” .
In general, content validation consists of “showing that the test items are samples of the universe in which the researcher is interested”, proving that this sample is indeed representative. A measurement of any kind is valid when it actually measures what it is proposing to measure. The researcher, when defining a method and a sample for a given study, must pay attention so that external factors do not exert any influence on the variables involved, under penalty of having their final results deviated in a biased way. Some bias or trend can occur in several aspects of the research, not only in the definition of the method and the sample.
The idea of validation also involves the concern with a neutral way of writing the questions of an instrument, the way of practicing the interviews for data collection, recording, information processing and dissemination of results.
In the previous figure, it can be seen that in the zone of low validity, although the pitches are well concentrated among themselves, the focus is shifted. This, in the practical case of a survey, could mean the existence of some tendency, since all records are being displaced from the central objective (as an example, one can quote an interviewer who induces the respondent to a certain answer).
Low interest rates cause people to hoard money, making output and employment stagnate.
The concept of the liquidity trap was first proposed by John Maynard Keynes. He believed that if interest rates were extremely low, people would hoard money in the believe that interest rates could only increase. This results in a stagnation in the level of investment, which would theoretically halt the growth of income and employment. For this reason, Keynes and his proponents maintained that fiscal policy, rather than monetary policy, would be the most effective tool for leaving the great depression.
It is first demonstrated in the preoperational stage. This stage is the 2nd stage in Piaget's theory. This stage starts around the age of 2 as children begin to make small talks and it lasts until about the age of 7. In addition, in this stage children starts to engage in symbolic plan and they learn to manipulate symbols.<span> </span>

What is Vasovagal Syncope?</h3>
When you experience vasovagal syncope, also known as vay-zoh-VAY-gul SING-kuh-pee, your body overreacts to certain stimuli, such as the sight of blood or intense emotional anguish. Another name for it is neurocardiogenic syncope. You experience a quick dip in blood pressure and heart rate when you have a vasovagal syncope trigger.
A abrupt drop in blood pressure that is frequently brought on by a reaction to anything is what causes vasovagal syncope. Your heart temporarily slows as a result of this. You can faint as a result of your brain not receiving enough oxygen-rich blood. Usually, vasovagal syncope is not a serious medical condition.
