This model was developed in a sample of 1000 working adults using the statistical techniques of Exploratory Factor Analysis followed by Confirmatory Factor Analysis by Structural Equation Modelling.

Subsequently, we learned from Douglass that his sample contained a few percent Af impurity.

We found no obvious effects due to preferred orientation of the crystallites in this sample nor would we expect to on the basis of the shape found from electron microscopic examination.

Spectra were obtained from a powdered sample having the shape of a right circular cylinder with a height-to-diameter ratio of 4::

Spectra were also obtained from a sample in a spherical container which was made by blowing a bubble on the end of a capillary glass tube.

The bubble was filled to the top and special precautions were taken to prevent any sample from remaining in the capillary.

Spectra were also obtained from a third sample of Af which had been diluted to three times its original volume with powdered, anhydrous alundum ( Af ).

A sample of Fraction Af from group O plasma was dissolved in starting buffer, dialyzed against this buffer and subjected to chromatography using the gradient shown in Fig. 2.

For purposes of sample selection only ( individual tests were given later ) we obtained group test scores of reading achievement and intelligence from school records of the entire third-grade population in each school system.

The final sample was not significantly different from a normal distribution in regard to reading achievement or intelligence test scores.

It was compiled as a control sample to determine if the opinions and practices of companies on the lists submitted by the members of the Aerospace Industries Association were materially different from those of other small firms selling to defense programs.

A test result ( calculated from the null hypothesis and the sample ) is called statistically significant if it is deemed unlikely to have occurred, assuming the truth of the null hypothesis.

Argon ( αργος, Greek meaning " inactive ", in reference to its chemical inactivity ) was suspected to be present in air by Henry Cavendish in 1785 but was not isolated until 1894 by Lord Rayleigh and Sir William Ramsay in Scotland in an experiment in which they removed all of the oxygen, carbon dioxide, water and nitrogen from a sample of clean air.

A formula for calculating an unbiased estimate of the population variance from a finite sample of n observations is:

Consider the sample ( 4, 7, 13, 16 ) from an infinite population.

In the Restoration and eighteenth century, poetry written in couplets is sometimes varied by the introduction of a triplet in which the third line is an alexandrine, as in this sample from Dryden, which introduces a 6-5-6 triplet after two pentameter couplets:

This conditioning process is responsible that only about 5 % of the aspirated sample solution reaches the flame, but it also guarantees a relatively high freedom from interference.

* Atomization of the sample from a graphite platform inserted into the graphite tube ( L ’ vov platform ) instead of from the tube wall in order to delay atomization until the gas phase in the atomizer has reached a stable temperature ;

These spectra are then multiplied with a factor to match the intensity of the sample spectrum and subtracted pixel by pixel and spectrum by spectrum from the sample spectrum using a least-squares algorithm.

Hardware from other vendors often used sample rates as high as 8192 Hz, often integer factors of video clock signals.

Technically, the method is destructive in nature removing ions from a sample surface in order to image and identify them, generating magnifications sufficient to observe individual atoms as they are removed from the sample surface.
