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.

Twinkl was founded by husband and wife Jonathan and Susie Seaton. [2] [3] Susie, a primary school teacher, had noticed there was a lack of ready-made, high-quality educational materials and classroom content available to teachers.
[2] [3] Estimation statistics is sometimes referred to as the new statistics. [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]
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 ...
The New International Version (NIV) is a translation of the Bible into contemporary English. Published by Biblica, the complete NIV was released on October 27, 1978 [6] with a minor revision in 1984 and a major revision in 2011. The NIV relies on recently-published critical editions of the original Hebrew, Aramaic, and Greek texts. [1] [2]
In statistics, the method of estimating equations is a way of specifying how the parameters of a statistical model should be estimated.This can be thought of as a generalisation of many classical methods—the method of moments, least squares, and maximum likelihood—as well as some recent methods like M-estimators.
