standard error

standard error (S.E.),

(in statistics) the variability in scores that can be expected if measurements are made on random samples of the same size from the same universe of populations, phenomena, or observations. The standard error provides a framework within which a determination of the difference between groups may be made. It is an element used in determining statistic significance by means of a wide variety of formulas and methods.

standard,

n that which is established by authority, custom, or general acceptance as a model; criterion.

standard deviation (SD),

n a computed measure of the dispersion or variability of a distribution of scores around a given point or line. It measures the way an individual score deviates from the most representative score (mean). A small SD indicates little individual deviation or a homogeneous group, and a large SD indicates much individual deviation or a heterogeneous group.

standard error,

n a measure or estimate of the sampling errors affecting a statistic; a measure of the amount the statistic may be expected to differ by chance from the true value of the statistic.

standard error of estimate,

n the standard deviation of the differences between the actual values of the dependent variables (results) and the predicted values. This statistic is associated with regression analysis.

standard error of the mean,

n an estimate of the amount that an obtained mean may be expected to differ by chance from the true mean.

standard of care,

n a written statement describing the rules, actions, and conditions that direct patient care. Standards of care guide practice and may be used to evaluate performance. Also referred to during the practice of dentistry when discussing quality of care.

standard operating procedure (SOP),

n a method of functioning that has been established over time in order to execute a specific task or react to a specific set of circumstances.

standard orders,

n.pl the rules, policies, procedures, regulations, and orders for the conduct of patient care in various stipulated clinical situations.

standard precautions,

n a set of procedures designed by the Centers for Disease Control and Prevention (CDC) to prevent the spread of known and unknown sources of infections. It formerly was called
universal precautions and applies to blood; body fluids, excretions, and secretions of the skin; and oral mucosa.

standard score,

n a derived score indicating the degree of deviation of an individual score from the mean using the standard deviation as the unit of measure.

standard

something established as a measure or model to which other similar things should conform.

bacteriological standard of meat

the standard bacterial count of meat beyond which local legislation forbids the sale or use of meat. The international standard is for <107/g of meat and that Salmonella spp. should not be present in more than one of five 25 g samples, all held at 95°F (35°C) or 68°F (20°C) for chilled meat.

standard bicarbonate

in blood gas analysis this is the plasma level of bicarbonate, under specified conditions, which eliminates the influence of respiration on the values obtained.

standard deviation

a measure of the dispersal of a random variable; the square root of the average squared deviation from the mean. For data that have a normal distribution about 68% of the data points fall within one standard deviation from the mean and 95% fall within two standard deviations. Symbol is σ.

standard error

the standard deviation of an estimate.

standard error of mean

the sampling variability of the mean.

standard international (SI) units

see Table 3.

standard population

a population not yet divided into classes; the population against which each of its constituent classes can be compared.

standard Salmonella pullorum strains

strains that contain only small amounts of 12₂ antigen.
