Accuracy refers to how close the results are to the established (or predicted) values. Experimentally, accurate results are evidence that the procedure worked as expected and that the combined error from all sources (instrumental, environmental, and human) is low.
Precision refers to how close the results are to each other. Highly precise results will indicate that the experiment was run (nearly) identically each time, though it will not guarantee accuracy.
Then they have precision but not accuracy.
Theories are observations held to be true based on their application to observation and proven scientific laws.
because i a theory is someones idea of what happend, that is debaitable with many diffrent ideas. but a scientific law is what is it.
A scintific law is a statement that describes what scientisis expect to happen. A scintififc theory is a well-tested explantion for a range of observations. This answers the question '' How Does Scientific Law Differ From Scientific Theroy?''
The enlightenment and the scientific revolution resemble each other in that they both are ways that humans of that time assess their place in the natural world.æ They differ in that one is based on scientific measuresæand one is based on religous or philosophical measures.æ
Accuracy is the tendency for a measurement to be correct. A more accurate measurement will be closer to the true value than a less accurate measurement. Precision is the tendency to come to the same measurement under the same conditions on multiple occasions. A precise measurement may not be accurate, but can be reproduced time after time and give the same (or sImilar) result.
A thermometer says the temperature is 34 degrees ceentigrade. The divisions are so close you could only decide it is 34 rather than 33 or 35. So its precision is one degree. If the specification for that thermometer is plus or minus 3 degrees then you only really know it is between 31 and 37. If its precision is plus or minus one degree you know it is between 33 and 35.
Consider someone firing a rifle at a target. If their shots centre around the bullseye, they were accurate, even if the scatter is quite large. If the scatter is very small (i.e. all the shots are very clustered) they were very precise - even if that cluster is far from the bullseye. So accuracy: how on target are you. Precision: How much spread is there around the target?
Then they have precision but not accuracy.
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
would your vital capacity measurement differ if you performed the test while standing
How does the project audit differ from the performance measjrement control system
Theories are observations held to be true based on their application to observation and proven scientific laws.
Scientific names never differ among scientists.
This a Study Island Question. The answer is "Scientific Theories are supported by evidence or data."

There are no standards of measurements. A measurement is an approximation or an estimation of an exact value. A number is an exact value such as one pencil or two cars.
