The spelling of "by estimation" uses the International Phonetic Alphabet (IPA) to represent each sound. The first word "by" is spelled /baɪ/ with the "b" and "y" creating the consonant-vowel-consonant pattern. The second word "estimation" is spelled /ˌɛstəˈmeɪʃən/ with the "e" in "estimation" pronounced as a schwa sound, and the consonant sounds "s," "t," "m," and "sh" creating a combination of unvoiced and voiced sounds. The spelling matches the pronunciation of each sound when combined to form the complete phrase.
By estimation is a phrase used to indicate an approximate or rough calculation or measurement of something. It refers to determining a value, quantity, or size through an educated guess or an opinion based on available information, rather than an exact and precise measurement.
In various contexts, by estimation is often used when it is not possible or practical to obtain an accurate measurement or data. It suggests that the value or quantity being mentioned is not exact but provides an estimate or an approximation that is considered to be reasonably close to the actual figure. This estimation is typically made based on knowledge, experience, or analysis of available information.
By estimation is frequently used in mathematical or scientific contexts when precise measurement or data is not easily obtainable. It allows for a degree of flexibility and acknowledges the inherent uncertainty in arriving at an exact figure. It is also commonly used in fields such as construction, engineering, economics, and statistics, where estimating values, costs, quantities, or proportions play a crucial role.
Overall, by estimation serves as a useful phrase to acknowledge that a figure or measurement is not known with certainty but is a close approximation based on judgment, inference, or available data.
The phrase "by estimation" is derived from the Latin word "estimatio", which means "a calculated or estimated value". The word "by" in this context indicates that something is being done or determined based on estimation or calculation. Thus, "by estimation" refers to something that is ascertained or evaluated using a method of estimation rather than precise measurement.
