Guesstimate is an informal English portmanteau of guess and estimate, first used by American statisticians in 1934 [1] or 1935. [2] It is defined as an estimate made without using adequate or complete information, [3] [4] or, more strongly, as an estimate arrived at by guesswork or conjecture.
An estimate that turns out to be incorrect will be an overestimate if the estimate exceeds the actual result [3] and an underestimate if the estimate falls short of the actual result. [ 4 ] The confidence in an estimate is quantified as a confidence interval , the likelihood that the estimate is in a certain range.
A report, commissioned by The Leadmill's legal team, estimated the cost of getting the venue back up and running would be about £4.7m, although Mr Madden said he believed it was a "£2m project".
In statistics, an estimator is a rule for calculating an estimate of a given quantity based on observed data: thus the rule (the estimator), the quantity of interest (the estimand) and its result (the estimate) are distinguished. [1] For example, the sample mean is a commonly used estimator of the population mean. There are point and interval ...

[3] [4] [5] The primary aim of estimation methods is to report an effect size (a point estimate) along with its confidence interval, the latter of which is related to the precision of the estimate. [6] The confidence interval summarizes a range of likely values of the underlying population effect.
