Accuracy is how close to the truth and precision is how narrow the the range of uncertainty or error. For example in guessing weight, of 150 # person, an accurate guess could be 140 # +- 15 #. An inaccurate guess would be 145# +- 2#. The first guess is accurate but not precise, the second is inaccurate but more precise.
What else can I help you with?
Can a measurement be precise without being accurate?
Yes, a measurement can be precise without being accurate. Precision refers to how close repeated measurements are to each other, while accuracy refers to how close a measurement is to the true value. It is possible for measurements to be consistently close to each other (precise) but consistently off from the true value (inaccurate).
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.
How do you explain how results can be precise but not accurate?
Results can be precise to the exact feat done. The results of a lab test are precise to everything that influenced, or interfered with the end result. The results of the same lab test may not be accurate for what is it being tested for.
What is the angle declination in surveying?
Angle declination in surveying refers to the difference between the true north and the magnetic north at a specific location. It is important to account for this declination when using compasses or other magnetic instruments to ensure accurate measurements and calculations.
Who invented the first tripod?
There is no accurate or precise answer as to who has invested the first known tripod in history. It's assumed that it can be dated back to Ancient times, although the details are unknown.
What is the difference between acurtate and precise?
An accurate answer to a question answers the question. The precision depends on the level of accuracy of the answer.
What is true if a digital scale reports a 10kg weight as weighing 8.975 kg?
The scale is precise but not accurate. (APEX)
What is the difference between an accurate and a precise measurement?
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
What is the difference between Precise and Concise?
precise is precise and concise is concise
Can a number be accurate but not precise?
no only if it is precise it is accurate
What is the difference between ordinary spirit levelling and precise levelling?
Ordinary spirit levelling uses a spirit level to measure height differences between points, whereas precise levelling involves more precise instruments like a digital level or automatic level to achieve higher accuracy in measurements. Precise levelling is typically used for engineering and construction projects that require more accurate measurements.
What are accuracy and precision and what is the difference between accuracy and precision?
Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.
What is the difference between atleast and atmost in probability?
The difference between "at least" and "at most" is not restricted to probability. The difference is simply one between the precise meaning of the phrases in every day English language.
What is the difference between accuracy and precision in scientific measurements?
Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close repeated measurements are to each other. A measurement can be precise but not accurate if it consistently misses the true value by the same amount. Conversely, a measurement can be accurate but not precise if the measurements are spread out but centered around the true value.
What is an example of being precise but not accurate?
An example of being precise but not accurate is measuring the length of a table as 150.0 centimeters when the true length is actually 160 centimeters. The measurement is very specific and consistent, indicating precision, but it does not reflect the true value, demonstrating a lack of accuracy. This scenario highlights the difference between consistently obtaining the same result and obtaining the correct result.
Are 76.48 cm 76.47 cm and 76.59 accurate or precise?
These numbers are precise, as they are all close together. If any one of these are accurate, then this group of numbers can be considered precise and accurate.
Is 0.25ml the same as 0.2ml?
No, 0.25ml is not the same as 0.2ml. The difference between the two measurements is 0.05ml. In terms of volume, this may seem small but in certain contexts, such as precise medical dosages or laboratory measurements, this variance can be significant. It is important to be accurate and precise when dealing with such small measurements to ensure proper outcomes.
