What are examples of inaccurate but precise results?
Asked by: scraper | Last update: August 23, 2026Score: 0/5 (0 votes)
Precision refers to how close measurements or data points are to each other. Accuracy refers to how close they are to the true value.
What is an example of precise but not accurate?
Precise but not accurate examples involve consistently repeated, reliable measurements that are far from the true value due to a systematic error or bias. Common examples include a clock running consistently 10 minutes fast, a scale consistently weighing items 5 lbs heavy, or darts clustering far from the bullseye.
Can you be precise but inaccurate?
Yes, you can absolutely have precision without accuracy.
What is an example of false precision?
The false precision fallacy (also known as fake precision or over-precision) is the error of providing exact, highly specific numbers for quantities or concepts that are inherently inexact or impossible to measure so accurately. It is typically used to make an argument, estimate, or claim sound more authoritative, scientific, and trustworthy than it actually is.
How can results be precise but not accurate?
A measurement is precise when repeated readings are highly consistent, even if they are all incorrect. It is only accurate if the average of those readings is close to the true value. Precision reflects reproducibility; accuracy reflects correctness.

What are some examples of precision in real life?
More Examples
If the thermometer continuously registers the same temperature for several days, the measurement is also precise. If you take the measurement of the mass of a body of 20 kg and you get 17.4,17,17.3 and 17.1, your weighing scale is precise but not very accurate.
How to tell if results are accurate or precise?
Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other.
What are the 10 common fallacies?
Logical fallacies are flawed arguments that undermine the logic of a discussion. They can be deceptive, often sounding convincing while lacking genuine evidence or sound reasoning.
What are examples of false positives?
A false positive is an incorrect test result that wrongly indicates a condition or feature is present when it objectively is not. It is essentially a false alarm.
What are some misleading statistics examples?
Misleading statistics occur when data is intentionally manipulated or accidentally misinterpreted to present a false or exaggerated narrative. They often rely on technically "true" numbers that are presented out of context, or use flawed methodology to guide the audience to a specific conclusion.
Can you be accurate and precise at the same time?
A measurement system can be accurate but not precise, precise but not accurate, neither, or both. For example, if an experiment contains a systematic error, then increasing the sample size generally increases precision but does not improve accuracy.
What is misleading precision?
False precision (also called over-precision or spurious accuracy) is the error of presenting numerical data or statistics with a level of exactness that the underlying evidence or measurement methods do not actually support.
What does it mean to be accurate but not precise?
You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision.
Can you be precise but still inaccurate?
Yes, you can absolutely have precision without accuracy.
What are 10 examples of measurement in our daily life?
Time, size, distance, speed, direction, weight, volume, temperature, pressure, force, sound, light, energy—these are among the physical properties for which humans have developed accurate measures, without which we could not live our normal daily lives.
Which of the following best represents accuracy but not precision?
Answer: A Dartboard showing the darts scattered far from each other and far from the bull's-eye (Option A) best represents accuracy but not precision.

What is precise vs accurate vs reliable?
Accuracy is how close a measurement is to the true value. Precision is how close repeated measurements are to each other. Reliability is the consistency of a measurement or experiment over time, meaning it produces similar results upon repetition.
When to use accurate and precise?
Both accuracy and precision reflect how close a measurement is to an actual value, but they are not the same. Accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value.
What is a good example of precision?
Precision is the reproducibility and consistency of repeated measurements or actions. It indicates how close multiple attempts are to each other, even if they are far from the correct target.
What is top 1 and top 5 accuracy?
Top-1 accuracy and Top-5 accuracy are performance metrics used in machine learning (particularly image classification) to evaluate how well a model guesses the correct category for a given input.
What are some things that are precise?
Precision is the exactness, reliability, and level of detail in a measurement or action. It focuses on repeatability—getting the exact same results or providing highly specific data.
How common are false positive results?
Some tests have false positive rates of 1 to 5 percent, while others may be higher. Tests for rare conditions typically have more false positives than true positives due to the low prevalence of the disease in the general population.
What are three problems with a false positive result?
Potentially stressful, expensive and even dangerous to a patient,2 false positives can also skew medical data and put an extra burden on healthcare facilities. This is why tests need to be both accurate and reliable!
What can give a false positive?
A false positive happens when a test incorrectly detects a substance or condition that isn't actually present. Different tests look for specific markers in your body, and various outside factors can interfere with the chemistry, tricking the test into a positive result.
