What is post stratification?
Post stratification is a statistical technique used to improve the precision of estimates by adjusting sample weights based on known population characteristics. It involves dividing the sample into subgroups (strata) based on certain characteristics and then adjusting the weights of each subgroup to better reflect the overall population. This helps to reduce bias and improve the accuracy of estimates in survey sampling.
What percent of Egypt's population is poor?
about half of the Egyptian population is poor.
The accuracy of a poll is usually expressed in terms of?
The accuracy of a poll is usually expressed in terms of margin of error, which indicates the range within which the true value is expected to fall. It is typically reported as a percentage.
What is the synonym of the word poor?
A synonym for "poor" is "impoverished" or "destitute."
What is another name for a poor farmer?
A poor farmer is sometimes referred to as a subsistence farmer.
Which of the following best describes this image?
Poor accuracy Good precision
How can results of an experiment have a good accuracy by very poor precision?
An experiment can have good accuracy but poor precision if the average of the results is close to the true value but the individual measurements are widely spread out. This could be due to systematic errors that affect all measurements in a similar way, leading to good accuracy, but random errors that cause variation between individual measurements, resulting in poor precision.
Ask us anythinghich of the following is an example of an archery contestant showing good precision but poor accuracy?
An archery contestant who consistently groups their arrows tightly together but consistently misses the bullseye would be an example of showing good precision but poor accuracy. Precision refers to how close a set of measurements are to each other, while accuracy refers to how close those measurements are to the true value.
What is an example of an archery contestant showing good precision but poor accuaracy?
Accuracy implies that there is no deviation from the desired result. Precision implies a consistent closeness to the desired result. An archery contestant whould show poor accuracy because the arrow is always off the target center. Good precision because it is always close to the target center.
Poor precision in scientific measurement may arise from?
poor precision in scientific measurement may arise?
Define accuracy and precision?
Accuracy and precision are synonyms. They both mean without error, they are exactly right, No more and no less.
What is precision?
Precision is a writer's attention to accuracy in world choice.
Can accuracy depend on the precision of the instrument?
Yes, accuracy can depend on the precision of the instrument. The precision of an instrument determines the level of detail and resolution in measurements, while accuracy refers to how close the measured value is to the true value. Higher precision can improve the accuracy of measurements by reducing random errors, but it does not guarantee accuracy if there are systematic errors present in the instrument.
How accurate is the speedometer on a Trek bike?
The accuracy of a speedometer on a Trek bike can vary, but in general, they are designed to be fairly accurate. However, factors such as tire pressure, wheel size, and calibration can affect the accuracy of the speedometer. It is recommended to periodically check the accuracy of the speedometer using GPS or other methods to ensure it is providing reliable information.
Are precision and accuracy the same?
No because precision is when you trie to put your efeert toit
What is the definition of precision?
precision is a writers attention to accuracy in word choice. (apex)
Is accuracy or precision related to standard error?
Standard error is a measure of precision.
