The mean is an estimated value because it is calculated based on a sample of data rather than the entire population. Sampling variability can cause the mean of a sample to differ from the true population mean. Additionally, the mean is sensitive to outliers and skewed data, which can further affect its accuracy as an estimate of the true population value.
The mean can be a true value. The mean height of the members of my family will be a true value.
However if my family is used as a (non-random) sample to represent all humankind, the mean will not be the true value but an estimated value. The accuracy of that estimate will depend on how representative of humankind my family is - at least in their heights.

Is it true that in an answer that has four significant figures two are estimated and two are known?
False, one is estimated and three are known
Is it true any score with value less than the population mean will have a negative z-score?
Yes. If a score is below the mean, the z score will be negative.
How do you write an estimate range?
Estimate the minimum value, A. Estimate the maximum value, B. The estimated range is from A to B.
What is the best estimated for the value of 38950 divided by 230?
The best estimated value is the exact answer since anything else can be improved upon with more effort.
How a measured value is reported in terms of known and estimated digits?
Significant Figure.
What is pi hat in statistics?
Consider a distribution with an unknown parameter pi. If the true value of pi is not known but has been estimated, then the estimated value is usually denoted by pi-hat. This is to distinguish between a known parameter and an estimated one.
What does estimated mean in math?
To make an educated guess. for instances if you were asked to estimate half of 1426, you would round down to to 1400, and half that which is much easier. Half of that that is 700, therefore you would estimate the answer to be around 700.
What is absolute error?
Absolute error is the difference between an estimated or measured value and it's actually value.For Example:To determine the absolute error you would have to have a measurement or an estimate of whatever this object is. At which point you would take the difference between the estimated value and the actual value.For example: 21.571 is the True value 20.000 is the Recorded Value.Thus: (True value) - (Recorded Value) = Absolute error (21.571) - (20.000) = 1.571
Hellenistic scientist who estimated the value of pi?
Archimedes estimated the correct value of pi
What does accuracy mean in math terms?
It is a measure of how close the calculated value is to the true value.
Another name for the mean of a probability distribution is its expected value true or false?
Yes, it is true.
What are the terms depreciable value salvage value and estimated life mean?
Depreciable Value: It is the value of asset up to which any asset can be depreciated. Salvage Value: It is the value which a company can get on sale of fully depreciated asset. Estimated useful Life: It is that life of an assets which a company determine at the time of purchase for which an asset can be utilized in business to generate revenue.
How does a measurement is to the true or accept value?
The accuracy of a measurement is determined by how close it is to the true or accepted value. This can be assessed by comparing the measured value to the known value, using statistical methods like mean or standard deviation. A measurement is considered accurate if it falls within an acceptable range of the true value.
Does taking something for granted mean that you are underestimating it?
It means that you are ignorant of its true value
Can I get an estimated value of Condo?
You can get an estimated value of a condo by comparing other homes that were on sale in order to find a reasonable price for the condo.
What is an estimated average?
An estimate is an approximate calculation or judgment of the value, number, quantity, or extent of something. An average is a number expressing the typical value in a set of data, most commonly the mean, which is calculated by dividing the sum of the values in the set by their number. An estimated average is a guess.
What does it mean to have a high percentage error?
It means that, relative to the true value of whatever you are trying to measure, the estimated (or calculated) value is quite a long way off.If the real value of something is 5 but is measure as 7 the absolute error is 7 - 5 = 2, but the percentage error is 100*2/5 = 40%If the true value is 100 and it is measured as 103, the absolute error is 103 - 100 = 3 which is greater than before. But the percentage error is only 100*3/100 = 3%.
