One of the mysteries of the English language finally explained.
1technical A numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation.‘there are three parameters by which a speaker is able to modify the meaning of the utterance—pitch, volume, and tempo’

- ‘Now we need to optimize the system and improve its operation parameters and design.’
- ‘The first circuit is configured to monitor an electrical operating parameter associated with operation of the CAN bus.’
- ‘The programming uses script files that contain specific system parameters to operate in each of these modes.’
- ‘The set of code modules includes code modules associated with a plurality of system configuration parameters.’
- ‘An operator can input the parameters that define the geometry of the valve seat profile.’
- 1.1Mathematics A quantity whose value is selected for the particular circumstances and in relation to which other variable quantities may be expressed.
- ‘As gene diversity is a continuous variable, the expected value of the parameter was calculated using a sliding window of 0.0125.’
- ‘Choosing different values for the various parameters in the equation he then tried to investigate when situations were stable and when they were unstable.’
- ‘The x-axis is the value of the selection parameter in the PRF model under which the data were simulated.’
- ‘On the other hand, keeping m and n fixed for a few trials leaves a lot of room to experiment with the third parameter even for small values of m and n.’
- ‘The real effort goes into testing these hypotheses and calculating the true values of parameters such as N.’
- 1.2Statistics A numerical characteristic of a population, as distinct from a statistic of a sample.
- ‘The normal curve approach to inference begins by asserting a null hypothesis that is expressed using population parameters.’
- ‘This will remind test users that the reliability coefficient in hand is not the population parameter and that the reliability estimate is affected by sampling error.’
- ‘Typically, polymorphism in a sample is needed to perform those tests and estimate population parameters.’
- ‘The spiral pattern is sufficiently regular that it leads to a numerical parameter characteristic for the species, called its divergence.’
- ‘Such a ‘rate’ can be modeled statistically by the probability parameter of a binomial distribution.’
2A limit or boundary which defines the scope of a particular process or activity.‘the parameters within which the media work’

- ‘Such a voluntary approach is limited to the parameters the company sets for itself.’
- ‘One of the main benefits of a home birth is the amount of control a mother can exercise over the location and parameters of the birthing process.’
- ‘First, I do not accept the framework you outline above as limiting the parameters of our debate.’
- ‘However, I can't get away from the fact that my guiding parameters are somewhat limited by my lack of motoring knowledge.’
- ‘And so, media debate is restricted within tightly constrained parameters that serve capital, but not democracy.’
Mid 17th century: modern Latin, from Greek para- ‘beside’ + metron ‘measure’.
