Task 8. Decide what parts of speech the words in bold type are.

1. If we have to measure the temperature we can say it is 10 degree C.

2. An ounce is a measure of weight.

3. We might measure the length of an object as 2.34 meters plus or minus 0.01 meter, with a 95% level of confidence.

4. There is only one way to determine and size a value.

5. We have to compare it with a known sizeof the same type.

Task 9. Read the text and decide if the statements below are true (T) or false (F):

The word measurement comes from the Greek "metron", meaning limited proportion.

Measurement of any quantity involves two parameters: the magnitude of the value and unit of measurement. Measurement is the estimation of the magnitude of some attribute of an object, such as its length or weight, relative to a unit of measurement. For instance, if we have to measure the temperature we can say it is 10 degree C. Here the value “10” is the magnitude and “C” which stands for “Celsius” is the unit of measurement.Measurement could also include such things as assessment of attitudes, values and perception in surveys or the testing of aptitudes of individuals.

The purpose of measurement is to provide information about a quantity of interest - a measurand. Metrology is the scientific study of measurement.

No measurement is exact. When a quantity is measured, the outcome depends on the measuring system, the measurement procedure, the skill of the operator, the environment, and other effects.

In science, where accurate measurement is crucial, a measurement is understood to have three parts: first, the measurement itself, second, the margin of error, and third, the confidence level - that is, the probability that the actual property of the physical object is within the margin of error. For example, we might measure the length of an object as 2.34 meters plus or minus 0.01 meter, with a 95% level of confidence.

The act of measuring often requires an instrument designed and calibrated to compare the object to some standard, such as a meter or a kilogram. Examples are a thermometer, speedometer, weighing scale, or voltmeter.

Surveys and tests are also referred to as "measurement instruments" in academic testing, aptitude testing, voter polls, etc.

The famous Swiss mathematician Leonard Euler (1701–1783) described the process of measurement: “There is only one way to determine and size a value. We have to compare it with a known size of the same type. Physics is nothing else than a science, looking for methods for the measurement of values.” 250-year-old definition is still valid today.
