Why is it good to have a high sample size?
It increases the accuracy of the estimation and reduces the associated error range.
Differentiate accurate from precise in measurement?
Accuracy is when the result is close or equal to the actual value or expected result. Precision is when multiple results are within the same or very close value. With multiple results, you can have accuracy and precision if the results are on target, and all within a very close range. However, if the results have quite a bit of deviation among them, but the average result is on target, then you have accuracy, but low precision. If multiple results are way off target, but are all within a close range of each other, then you have low accuracy and high precision. If the multiple results are all over the place, and the average result is off target, then you have low accuracy and low precision. For example, it helps to imagine a dart board with a few darts. If all the darts are together after being thrown, that is precision. When the thrown dart is close to the bullseye, that is accuracy. IF the darts are all close together and all on the bullseye - that is accurate and precise...if they are all close together, but way off the bullseye, then that is precise but NOT accurate, and so on...
What amount of sampling error is acceptable in a national sample of 1500 to 3000 respondents?
There can be no set value. An acceptable level of sampling error for a company making high precision machine parts is likely to be very different from the sampling error for household incomes, for example.
What is a precise measurment?
A precise measurement is an exact measurement.How long,how tall how wide. EXAMPLE-12X5X24Precision refers how close measurements of the same thing are to each other. A precise measurement is one that is similar or the same as previous measurements. A precise measurement does not need to be accurate.precise measurements may not be accurate but will agree with each other. Characteristic of precision is low standard deviation. It is not in all cases proof of accuracy though
What is the difference between low percent error and high percent error?
The difference between low percent error and high percent error is one is low and the other is high
How are accuracy and precision alike?
"Precision" is high when you get the SAME answer every time. Accuracy is high, when you get the CORRECT answer. You can hit a target in the same place everytime which is very HIGH precision; however, if that place is not the "Bulls Eye", your accuracy is lousy.
Throwing three darts and hitting inside the bulls-eye each time is an example of?
high accuracy and high precision.
Throwing three darts and hitting inside the bull's-eye each time is an example of?
high accuracy and high precision.

What are the benefits of using automated techniques for manufacturing electric circuits?
I high degree of precision, accuracy and speed as well as reduced waste due to manufacturing errors.

How do you proof a cube volume?
The proofing of volume can be performed through basic and advanced forms of instrumentation. If accuracy and precision is not an issue and estimate is sought the cube can be slowly filled using known measurements. If high precision is needed the use of volumetric flasks can be used.
What is accuracy give some example?
Accuracy refers to how close you are to the real answer. This is usually used in measurements. For example: The weight is 55.5kg. The accurate measurement will be 60kg which is close to the real answer.
In a Sports analogy define precision and accuracy?
There are many sports that need accuracy to win but the sport I think of the most when it comes to accuracy is football. Quarterbacks have to be exact on most of their throws. The difference between one inch in football is a touchdown or an interception. Saying this it is important for Quarterbacks to keep improving their accuracy if they want to compete on a high level.
