## What is a true parameter?

A confidence interval allows us to state that the true value of a parameter lies within a range of values determined from the sample at a specified level of confidence (90%, 95%, 99%, etc.). The confidence level does not tell us that the probability that the statistic is the true estimate of a parameter is, say, 95%.

## What is a good percent error?

Explanation: In some cases, the measurement may be so difficult that a 10 % error or even higher may be acceptable. In other cases, a 1 % error may be too high. In most cases, a percent error of less than 10% will be acceptable. …

Percent errors tells you how big your errors are when you measure something in an experiment. Smaller percent errors mean that you are close to the accepted or real value. For example, a 1% error means that you got very close to the accepted value, while 45% means that you were quite a long way off from the true value.
