How do you keep your measurements consistent even if you are not precise or accurate?

You could do it by saying that all your measurements were 10 centimetres - irrespective of what they actually were. That would be neither precise nor accurate but it sure would be consistent!

Explain why is a highly precise measurement doesn't not always mean a highly accurate one?
Accurate means how close the measured value is to the real, actual value. Precise means how reproducible the measurement is. So, if the real value is 1.00, and you measure it to be 0.785, and every time you measure it, it comes out the same (0.785), then the measurement is VERY precise, but not very accurate.
What is the difference with precision and accuracy?
Accuracy refers to how close a measured value is to an excepted value. Precision refers to how close a series of measurements are to one another For example, if your experimental value is 15.63 and your values are... 12.84 13.02 12.96 They would be precise because they are close to one another but not accurate because they're not even close to the experimental value
what is the difference between accuracy and precision?
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
What measuring device use for size of the classromm?
A tape-measure could be used to measure a classroom. A metre length stick, or even pacing are other means that can be used. It rather depends on how accurate the measurements need to be.
Why are womens clothes size in even numbers?
Apparently, women's clothes sizes are in even numbers because of standardized measurements. When you cut cloth, you can standardize the measurements.
Is it possible for an observation to be accurate but not precise?
Yes, it is possible. Accuracy refers to how close an observation is to the true value, while precision refers to how close repeated measurements are to each other. An observation can be accurate if it is close to the true value, even if the measurements are not precise and vary widely.
Can measurements be accurate and not precise?
Yes, measurements can be accurate but not precise. Accuracy refers to how close a measurement is to the true value, while precision refers to how close multiple measurements are to each other. So, a measurement can be accurate if it is close to the true value, but not precise if it varies widely from repeated measurements.
How does stirring water make results more reliable?
Stirring water helps to ensure an even distribution of solutes and temperature throughout the solution, leading to more consistent and accurate measurements. This reduces potential areas of variation and improves the reliability of experimental results by minimizing sources of error.

Why would a scientist use a graduated cylinder instead of beaker?
A scientist would use a graduated cylinder instead of a beaker when they require more precise volume measurements. Graduated cylinders have marked graduations that allow for more accurate volume readings compared to beakers, which do not have precise measurement markings.
What problems could result from incorrectly converting measurements from the system to another?
Incorrectly converting measurements from one system to another could result in errors in calculations, leading to inaccurate data and potentially incorrect decisions being made based on that data. This can cause misunderstandings, inefficiencies, and even safety hazards in fields where precise measurements are crucial, such as science, engineering, and construction.
What is the prefix for precise?
-Curo is the suffix even though it is not included in the word. -Curo means to take care of.
How accurate is the laboratory thermometer?
Laboratory thermometers are typically very accurate, with some having an accuracy within ±0.1°C or even better. However, accuracy can vary depending on the calibration and quality of the specific thermometer being used. Regular calibration and maintenance are important to ensure accurate temperature measurements.
When is a measurment accurate?
Never: A measurement made is always an approximation. We can get very close to being accurate with our measurements, but never fully 100% accurate. This is not the fault of the person measuring, or what tool they are using to measure with, but it is a natural law that we (anyone, even superior aliens to humans) cannot ever fully make an absolutely accurate measurement.
Why are polls used so often even though they aren't precise?
Even if they are not precise, they often give a good general idea.
Why should samples for melting point determination be finely powdered?
Samples should be finely powdered for melting point determination to ensure uniform heating and accurate results. Fine powder allows for even distribution of heat throughout the sample, leading to consistent melting behavior and precise measurement of the melting point. Unevenly sized particles can result in inaccurate readings and can affect the repeatability of the experiment.
