What does selectivity mean?

1 : of, relating to, or characterized by selection : selecting or tending to select. 2 : highly specific in activity or effect selective pesticides selective permeability of a plasma membrane. Other Words from selective. selectively adverb.

Subsequently What is the plural of selectivity? Noun. selectivity (countable and uncountable, plural selectivities) The quality of being selective, or extent to which something is selective.

What is the word for selective? Words related to selective

careful, choosy, discriminatory, fussy, judicious, scrupulous, discerning, eclectic, particular, persnickety, picky, select.

Beside above, What is specificity and selectivity? The key difference between specificity and selectivity is that specificity is the ability to assess the exact component in a mixture, whereas selectivity is the ability to differentiate the components in a mixture from each other.

What is selectivity and sensitivity?

Selectivity is the quality of a response that can be achieved without interference for any other substance. Sensitivity is how low can you detect the substance of interest.

What is the specificity?

Definition of specificity

: the quality or condition of being specific: such as. a : the condition of being peculiar to a particular individual or group of organisms host specificity of a parasite. b : the condition of participating in or catalyzing only one or a few chemical reactions the specificity of an enzyme.

What is selectivity sensor? Selectivity to a target gas A toward any interfering gas B is traditionally defined as the ratio of the sensor response to gas A to the response to gas B (Kalantar-zadeh, 2013). The selectivity of the sensor is defined as the ratio of its best response to its second-best response.

What is sensitivity and specificity? Sensitivity refers to a test’s ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed. The specificity of a test is its ability to designate an individual who does not have a disease as negative.

What is sensitivity in mechatronics?

It is the ratio of change in output (or response) of the instrument to change in input or measured variable. A higher sensitivity indicates that the system can respond to even the smallest input.

How do you measure selectivity? The selectivity of an index can be calculated by dividing the number of individual index values by the number of rows in the table. If the table has been analyzed, the selectivity of each column can also be individually examined by USER TAB COLUMNS.

What is specificity in PE?

Specificity – training must be matched to the needs of the sporting activity to improve fitness in the body parts the sport uses. … If you take a break or don’t train often enough you will lose fitness.

What is specificity training? What is specificity of training? It is training that is relevant and appropriate to the sport or functional task in order to produce the best effect. Specificity of training means taking the extra step from general training.

What is specificity in physical education?

In exercise: Specificity. The principle of specificity derives from the observation that the adaptation of the body or change in physical fitness is specific to the type of training undertaken. Quite simply this means that if a fitness objective is to increase flexibility, then flexibility training must…

What is specificity biosensors?

Specificity is considered the most essential quality of a biosensor, as it describes the sensor’s ability to differentiate between target and non-targeted biological entities in a sample.

What is selectivity in chemistry? Selectivity refers to the extent to which a method can determine particular analytes in mixtures or matrices without interferences from other components.

What is the difference between drug selectivity and specificity? For example a selective drug would have the ability to discriminate between, and so affect only one cell population, and thereby produce an event. Specificity, a term most often confused with selectivity, will be used to describe the capacity of a drug to cause a particular action in a population.

What does low specificity mean?

A test with low specificity can be thought of as being too eager to find a positive result, even when it is not present, and may give a high number of false positives. This could result in a test saying that a healthy person has a disease, even when it is not actually present.

What is specificity in machine learning? Specificity is defined as the proportion of actual negatives, which got predicted as the negative (or true negative). This implies that there will be another proportion of actual negative, which got predicted as positive and could be termed as false positives.

What does specificity mean in biology?

Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. … Each animal or plant species is special. It differs in some way from all other species… biological specificity is the major problem about understanding life.”

What is calibration in metrology? In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy.

What is high repeatability?

The repeatability is defined as the closeness of agreement between the results of successive measurements of the same measurand carried out subject to the following conditions: • the same measurement procedure, •

What is difference between resolution and sensitivity? RESOLUTION – the smallest portion of the signal that can be observed. SENSITIVITY – the smallest change in the signal that can be detected.

What does a high selectivity mean?

It’s a ratio between the number of values in a column, the COUNT, and the number of values that are distinct or unique. So something with a high selectivity means that the ratio is approaching 1 where as something with a low selectivity means it has a very low ratio value.

What does low selectivity mean? A lower selectivity value is better: it means fewer rows to scan and filter. Oddly, though, we say an index is “highly” selective if it has a low selectivity value. When a database plans a query, it’ll look in its index statistics and estimate how many rows the query will match.

What is a good selectivity index?

If the selectivity index is less than 0.1, the proteinuria is highly selective, and if it is more than 0.2, it is nonselective.
