blunder. Compare with systematic error, random error and gross error. A mistake is a measurement which is known to be incorrect due to carelessness, accidents, or the ineptitude of the experimenter. It's important to distinguish mistakes from errors: mistakes can be avoided. Errors can be minimized but not entirely avoided, because they are part of the process of measurement. Data that is mistaken should be discarded. Data that contains errors can be useful, if the sizes of the errors can be estimated.
a wrong action attributable to bad judgment or ignorance or inattention; "he made a bad mistake"; "she was quick to point out my errors"; "I could understand his English in spite of his grammatical faults"
An error or misunderstanding. A contract is voidable if there is a mistake that is mutual, material, unintentional and free from negligence, such as both parties honestly contracting for a different lot in a subdivision (mistake of fact). Innocent mistakes seldom serve to void a contract. A party cannot claim "mistake" to get out of a contract on the basis that he or she did not read the contract he or she signed and was therefore mistaken as to its material terms; neither ignorance nor poor judgment is a mistake of fact. Nor can a party claim mistake in not knowing the legal consequences upon signing the contract (mistake of law). When there is an ambiguity known by one party who fails to explain the mistake to the innocent party, the innocent party's interpretation generally will prevail.
In contract law a mistake is incorrect understanding by one or more parties to a contract and may be used as grounds to invalidate the agreement. Common law has identified three different types of mistake in contract: unilateral mistake, mutual mistake, and common mistake.
Refers to a belief of the contracting parties that is not in accord with existing facts. It is also a legal defense used in certain circumstances when a defendant may negate the required element of criminal intent. For example, a person who mistakenly takes another person's coat, believing it to be his or her own, will not be guilty of theft.
a fundamental mistake can void the whole contract. The mistake can be common to both parties eg they think they are buying and selling a car, which has been destroyed and neither is yet aware of this. Alternatively the mistake can be mutual eg where they are in fact thinking of entirely different cars but don't realise it. Lastly there can be a unilateral mistake where one party is mistaken and the other party knows they are but this can cross over into misrepresentation or even fraud.
Unlike mistake of law, which is not usually a defense, mistake of fact may sometimes offer exculpation (as in excuse) by allowing a criminal defendant some relief from liability for having broken the law.
